Hello. A few things to think about in your fish keeping journey: Change at least half the tank water every week. The more water you change, the healthier your fish. A small tank will require a couple of 50 percent water changes weekly. Don't put chemicals into the tank. Just the standard water treatment. Feed your fish a variety, but not too often. Once daily should be enough. If you're seeing fry in the tank, then a bit more is fine. But, just a bit. Planted tanks are nice, but you can still have a very nice looking tank with local driftwood and rocks. Planted tanks will take more work, so weigh the amount of work against the rewards. Goldfish are a great choice. With the proper care, they'll outlive just about all the other fish species. Most will get big, so give them at least a 55 gallon tank and don't keep very many. Koi aren't a good indoor fish. Unless, you can provide them with at least 250 gallons of water. Just some things to think about if you're thinking about getting into the hobby.

I agree with almost everything here except the feeding. Depending on the fish, once a day is not enough. Some fish actually need to feed almost constantly due to their stomach size or in the case of goldfish, a lack of a standard stomach to store food. Feeding once a day usually leads to more food in the filter than in the fish's stomachs. I prefer to use the "pizza pie" method. A normal feeding ( as much as a fish can eat in 1-2 minutes) 3 times per day will give you a base line for how much food your fish can eat in a day. Call that the whole pizza. Take that amount and slice it up like a pizza by the number of times you are going to feed. For example: feed twice a day, feed 1/2 of the total amount per day at each feeding. Feed 4 times a day, feed 1/4 of the total amount of food per feeding. Feed 8 times per day, feed 1/8 of the total amount per feeding. At the end of the day, no matter how many times you've fed, you have not over fed the fish or the tank. You'll see growth and health better by doing this. (y) It's also best to give a variety of food daily so only feeding once per day makes that hard to do.
You are definitely right with water changes. (y) (y) People hate doing them but the fish respond so much better when you do them. If you want the healthiest fish, give them the healthiest environment. That's water with no ammonia, no nitrites and no nitrates. Even if you use live plants to remove nitrates, replacing water replaces the micronutrients the fish are absorbing out of the water. There is no cheaper way of doing that than water changes. (y)

Hello again. Thanks Andy. You've brought up some very good points. Feeding the fish can be tricky. I've always felt that a little less is best for maintaining a steady and healthy water chemistry. Fish will always appear to be hungry. I've found if I feed a bit less, the fish are more actively moving around the tank looking for the bit of food the others have missed. I was taught that a fish that's a bit on the hungry side is healthier.

"A slightly hungry fish is a healthy fish" is something i often see quoted.
My Mentor told me way back when that "reducing feed to improve water quality is not the way to keep fish or any animal. If you want a healthy animal, you have to feed them." Other wise old sayings he told me are " A healthy water quality is maintained through water changes." and " A healthy fish is a breeding fish." By following these words of wisdom I've produced literally millions of fish for the aquarium trade. If you reduce feed or feed poor or low quality foods, breeders don't breed. I rarely suffered from that situation. ;)

Back then, we also had many fish that were wild caught so treating them with wild conditions was not the worst thing. It's why adding slightly cooler water during a water change spurred on fish to spawn because it replicated the rainy season which was when many species bred in nature. We even used Ice Cubes in the Cory breeding tanks to make them think a cold front was coming and that spurred them on to spawn. Wild fish also had a better more nutritious diet of insects or water bugs or fish flesh, crustaceans, etc. so they were used to infrequent feedings because the healthiest fish were getting what they needed through the diet while the unhealthy ones became food for other fish. They didn't always need a lot of food to survive or they were used to periods of low foods to basically go still to not expend the energy. Water flows were not always constant so the fish could rest in the pools or still water. But that was then, this is now. With so many fish in the hobby being farmed, they are fed many times during the day to ensure growth and health. ( We can talk about lack of culling at another time. ;) ) So these fish are accustomed to be fed frequently so they are not adapted to infrequent feedings. They burn up the caloric intake quicker because the water flow and temperatures in a tank are constant. They have no long periods of time to rest quietly. They are also getting a poorer quality diet in tanks as most people do not feed variety or quality due to financial constraints or lack of knowledge of the need. And now we even have so many diseases and resistant pathogens created on the farms that it's not really safe to keep farm bred fish and wild caught fish in the same aquarium anymore. :( So the reality is, like all things fish keeping, it's situational. For example, If you are feeding larger cichlids feeder fish, they will remain fairly sedentary while they digest their meal. That could be a couple of days depending on how much they were fed so they don't always need multiple feedings every day. On the other hand, take fish that are in constant motion ( i.e. Barbs or some Tetras) and they will burn up their food intake faster so they need more frequent feedings just to stay static. So there really isn't any one size fits all when it comes to all fish which is why using the " pizza pie" method works because at the end of the day, the fish does not overeat even if they are fed 3,5, 7 even 10 times a day. With every increase in number of feedings, there's a reduction in the amount fed at each feeding. They are consuming the same amount of food per day vs per feeding. (y)
My tanks got fed 3 times a day, everyday. ( I'm not a believer in the " fasting" method. ) They also didn't get fed the same food twice on any one day. One feeding was for ease ( usually flakes), one was meat ( usually live or frozen worms, bugs or shrimp) and the last meal of the day contained vegetation or foods with chiton ( either bloodworms, brine shrimp or Daphnia) so that it pushed out the day's feedings. I never had a bloating issue until I tried switching to freeze dried and pelleted foods. Today, I won't feed any of them anymore because I have done autopsies on some bloated fish and found clumps of these foods in the intestines. It was just disheartening to see.
So that's my story and my why. (y)
 
Hello Andy. Whoa! That's a lot of information. I've kept fish a long time and found there are several ways to approach the "Water Keeping" hobby. But they all boil down to the water. I say this because to be successful, you need to pay the most attention to the thing that makes up the largest part of the hobby and that's the water. My fish get fed sparingly. Just once a day or so with a variety of foods. Nothing special, just a variety. The water stays near nitrogen free and high in all the nutrients that come with a lot of clean, treated tap water. I've always followed the KISS approach to fish keeping. Keep it simple and you'll be successful.

Absolutely, there are many ways of keeping fish. I'm sure if you asked 6 people how they maintain their tanks, you'll get 6 different answer. ;) But you are right, the water is the most important which is why I get a bit pitterbed when I read the so called "experts" touting " No water changes" methods. Sure, the fish can live in those ways but they are definitely not the healthiest they can be. You may not see it in say, a neon tetra but you definitely will in fish like Discus or Angelfish or other medium and larger sized fish because their growth gets stunted. That's from a lack of vitamins and minerals the fish get from new water and their diets. There have been many experiments done over the decades that prove this out. I don't know if you know my history but I'm now 60 years of keeping fish as well as being in the pet industry for over 45 years with fish being my primary interest for 40 of those years. I took a detour from becoming a Veterinarian to stay in the pet business. My mentor, beside being a childhood friend of my Mother, was a certified Ichthyologist who owned the only pet store in their town and every fish he sold in the front of the store he was breeding in the back of the store. He took me under his wing when I was only 7 and by the time I was 9, I was already listed as a commercial fish breeder because he had me breeding a lot of his fish for the store plus selling the overages to the wholesalers. I have bred many families of fish ( and animals) so I have a good background on how to make most fish breed. So I follow my Mentor's method ( as I described in my previous post) because like everything in nature, their #1 goal in life is to reproduce and only the strongest, healthiest members of that specie are successful at it. I use that as my que.
In the end as a hobby, everyone's goals may not be the same. The KISS method is definitely a good one. It follows the old saying " The less you mess, the greater the success. " (y) The key tho is to start off with the right equipment, the right mixture of species and good healthy stock. After that, it's just habits and routines. The fish will show you if you are doing things right or wrong. (y) Now, if we could only get the farms to do more culling and produce healthier fish. 🙄
 
Hello Andy. Thanks for bringing us "up to speed" on your experience. We're fish and animal people as well. However, not to the extent you've been involved. We'll keep up on the water changes for sure. Not less than half every week. I keep several tanks between 45 and 300 gallons and a number of different fish from Guppies to Koi. We have a routine that we've been following since 1984, so I believe we have a well established system for keeping fish and whatever animal shows up at our door. Thanks again for the information and help!

I just wanted to let you know my theories are not my own but from people far more qualified than I at making them. My experiences have truly been an example of " If you do what I do with the same materials I use, you will get what I get." With all the different ways of fish keeping, there is no doubt that when one follows someone who is successful in this hobby, if they use the same materials ( same water parameters, water change schedules, foods etc), they should have the same successes no matter which method that is. (y)
Keep up the good work. (y)
 
You might get a kick out of this: In 1978, 3 1/2 years after I had moved from NJ to FL, my Mentor sent me this announcement of his new store. I truly believe it was an attempt to get me to move back up to NJ. ;) I already had a hatchery in Florida going so I wasn't moving back. LOL 1736443364028.jpeg
