I have bought and mostly killed :facepalm: three different "colonies" of Cherry Shrimp and it's driving me crazy. I'm think my first little colony of 15 died because of an ammonia spike. The second colony of 10 had a die off after I added a new plant to my tank, but I did manage to save three of them. One has just disappeared, another I found dead in the tank after two weeks. There is one lone survivor. Yesterday I received an order of a dozen Fire Red Cherry Shrimp. I tested my water before drip acclimating them and then added them to the tank last night. I lost 4 in a few hours and within 12 hours was down to 4 which is where I am right now. I have a Betta and a small and a larger mystery snail in the tank that were sold to me as Zebra Snails....a newbie mistake that I figured out when one of the snails began to grow incredibly fast. He is pretty big -- I would say bigger than a quarter but a bit smaller than a ping pong ball. I am wondering if this snail is producing too much ammonia for my 5 gallon Fluval Spec? My nitrites normally stay at zero, but I get high ammonia (.5 ppm) almost every day. (I've been testing daily since the first ammonia spike). This does not make much sense to me, but as I said I am a newbie at this. I did not know about fishless cycling until I already had bettas in my tanks. I do use Nutrafin Cycle with every water change and do at least weekly PWC's I also use Jungle or Seachem Prime as a dechlorinator. The tanks is fairly heavily planted IMO with a 4 nice stems anacharis, 3 stems bacopa caroliniana, 3 stems of jungle val, a med. java fern, 3x3 mat of java moss, 1 anubias nana, 2 anubias nana petite, a little peacock moss and a couple of cryptocoryne parva. Is the snail too big for this tank? I don't have a bigger tank for him. I have all very small tanks...5 gal., 4 gal. and 2, 2 gal. betta tanks. All Fluval. I honestly thought the snail was a nerite and that it would, at the most, end up the size it is now. I have only had it for about 5 weeks! I also have four more that are not growing as quickly as this one. He or she does seem to produce a lot of waste, sitting around and dropping poop almost every time I look at him. I only feed them extra when he seems really hungry and starts uprooting the plants to seemingly eat the roots! He really is like a bulldozer plowing through my tank but I have grown to adore the big fellow. Also is his ammonia producing poop the likely cause of my shrimp deaths? I am doing almost daily water changes right now despite the plantings. Any advice anyone has would be appreciated. I know someone will probably need even more details than I have provided. Please feel free to ask if I missed something crucial. Thanks for any help!!!! :banghead: :huh:
 
Daily spikes of ammonia that high? I would have to say you are either not cycled fully or your guess of being overstocked might be correct. Hopefully someone more knowledgeable can help you. I am pretty sure the ammonia is killing the shrimp though.
 
Yes the ammonia is killing the shrimp for sure, also the betta may be eating some. How long has the tank been set up, what test kit are you using?
 
Yeah those ammonia spikes are probably the cause. Ammonia and nitrite should always be 0 in a cycled tank. Any amount of either of those is toxic.

So here's what I would do. Go down to your LFS and get the littlest bottle of Seachem Stability. It has dosing instructions on the side which are very easy to follow. It'll be something along the lines of one capful per day. What the Stability product has is essentially the beneficial bacteria in spore form which, when diluted into your tank water, activates the bacteria and hopefully jump-starting your cycle. If your LFS doesn't stock Stability, then Petsmart has it. Petco doesn't stock it.

If you can't find Stability, the Tetra Safestart product is essentially the same thing. I'm a sucker for brand loyalty though and I love Seachem's other products so I just go with Stability. But you should head over and get a bottle of this stuff ASAP.

Red cherries are hardy little guys as far as shrimp go, so once you get your tank cycled and get those parameters in line, you'll be good. The only issue will be with your betta possibly eating baby shrimp, but having it as heavily planted as you say will most certainly help.

The tanks has been set up for 5 weeks. Like I said in that very long post, I learned about fishless cycling right after I put the betta in that tank. It was set up with a couple of plants and just the snails for a week before I got the betta. That's still current occupants beside one very tough red cherry shrimp and I have one or two of the latest shrimp alive. The snail has just grown so fast and produces so much waste that I am concerned about keeping him in that tank. I use the API Master Test Kit...the one with Nitrite, Nitrate, Ammonia and high and low PH tests. Everything is good except for that ammonia and I can actually smell the snail poop when I remove something from the tank. A few weeks ago before the snail got so big, the tank was actually more stable. I can agree that it may not be done cycling. I won't add any more shrimp until I can get the tank stable, but I am afraid I won't be able to stabilize it with such a large snail. :huh:

I thought Red Cherries were hardy until I killed so many! :nono: I feel horrible about it. I know the betta may eat some of the shrimp and my first order had such tiny shrimp that he, in fact, may have had a big meal of those. I never did find all of the "bodies"...just a couple. The last two orders had much larger shrimp and Joey (my betta) seems to stay away from them.

I do happen to have a small 1.69 oz. bottle of the Tetra Safe Start that I bought just to have on hand. I have no LFS and the nearest PetSmart is almost 40 miles. I order a lot of my stuff from Amazon and that's where I got this.

I am about to go do a water change. I know the ammonia is high without even testing because the shrimp are at the top of the tank sitting on some plants. I will add some of this when I do that change. Should I also add it daily? And what is your opinion on the snail? Does he need another home? This is the part that is driving me nuts. He may be my whole problem but I don't know it that's possible.

The Tetra Safestart needs to be added all at once. Seachem Stability is added usually one capful a day. Just take a look at the instructions on the back of the bottle and try to find an expiration date to make sure the Safestart is still okay.

I think you'll be fine with the snail in there once your tank gets cycled.

Thank so much, the bottle actually said 10 ml per 10 gallons of water on water changes, so I added the 10 ml to my 5 gallon. Do you think I should I go ahead and just dump the whole bottle in? I am going to order some of the Seachem from Amazon and should have it by Tuesday. I've only had the Safestart a couple of weeks so it's fine. I don't want to risk my fish or the snails....or the two shrimp I have left. One is the single red cherry saved from the 2nd group of shrimp. It must be tough! Had him a few weeks.
 
You don't really need the stability, just test your water daily and change as needed, your tank will finish it's fish in cycle soon enough. You really don't need the safe start either but if you already have it in hand than it couldn't hurt..
 
Wow! So I did a more than 50% water change about three hours ago. I decided to test the water and the ammonia is still at .25 ppm and the Nitrites turned dark blue (not light purple) so I have no clue what this means. I did use 10 ml of the Tetra Safe Start. Not sure if I should do another water change now or wait until tomorrow. Any more ideas! I do usually use Nutrafin Cycle. I have had another 4 gallon betta tank since last August and have always used Cycle with it. The water always test great in that tank....even with two smaller mystery snails! Geez!
 
If you have established filters just take one and swish it around in this tank!

The 4 gallon tank is a Fluval View and it uses those small carbon plus some white material filter cartridges (oddly, I have never really researched what they consist of). There's 2 and I change one of them every week. Should I stick one of those in the tanks when I change it this week? I have thought about it but wasn't sure that type of filter media would help boost bacteria. I am thinking about adding some sponge to that tanks filter compartment, but since it's been working for so long, I haven't really bothered to change anything yet. :fish1:
 
I did just look it up and the Fluval View filters are Carbon and Zeolite.
:blink: There are days that I wish I had stuck with one betta and one little tank. The planted aquariums and beautiful bettas I kept seeing made me want more. So now I want shrimp - and plants - and bettas. I thought the snails would be a good cleaning crew, but now, I'm not so sure! :facepalm:
 
Just grab one if those filters and shake it out in the tank or leave it in there over night, bb will get into the system that way..

Another thing to consider is that you really don't need to change your filters at all unless they are falling apart, and doing so could cause little mini-cycles in your tank. Just swish them in the old tank water when doing a WC and you should be good to go.

Probably not main problem but part of the anubias plant is toxic to shrimp. If you cut the plant it will kill some shrimps unless you immediately do a 50% water change. It is possible to keep Anubias plants with shrimps but it is quite risky.

Oh my gosh! I had no clue. The tank had a Nana and 2 Nana petite Anubias in it. I actually had a shrimp die off when I put the 2 Nana Petites in the tank and asked if anyone knew why. Should I remove these before I try shrimp again? I like the Anubias in the tank because they have the larger leaves and do well in low light. Any suggestions for a replacement plant???? :nono:

Thank you so much!

Thanks for the info... The Fluval View filters are little cartridges of zeolite and some batting type filter floss....They get VERY dirty in a week or so and restrict the flow of water. Can these just be washed? The ammonia and nitrite in that tank stay at 0 ppm...despite the frequent filter changes.
