So I went to petco today with my dad and he bought me a 28 gallon euro aquarium. It included a penguin 150 biofilter, stand, aquasafe water conditioner, 17 watt strip light hood, and free buy one get one free coupon for tetra food. My dad said he'd pay for the kit but I have to buy the substrate, decor, fish, heater, anything not included I need, etc. I'm going to buy super naturals sand, I'm not sure how much, jäger tru temp 100 watt heater, and I already bought some large black stones, I'm either going to use marimo balls and either more live plants or just artificial plants. I'm going to get a couple of natural looking caves and decor along with food and pure ammonia. What should I stock the tank with? I currently own a female betta I was going to put in there because she's in a 1 gallon bowl. I was also planning to get albino Cory catfish. How many should I get? I've heard they prefer schools. I have my heart set on getting albino Cory cats lol! Would they prefer sand, I also have my heart set on sand I will not use gravel! Also my mom wants something unique to put in it like snails, frogs, algae eater (I told her algae eater was out), something other than average fish. I've considered malasian trumpet snails and African dwarf frogs but snails multiply and the dwarf frogs like shallow waters because they're not good swimmers and need to constantly come to the top for air and they're very blind so they're fin nippers. What should I put in there for my mom? Maybe kuhli loaches but what are my other options? Thanks I don't want to overstock it at all I want maybe a 75 percent stocked tank and then when I get some experience stock it 100 percent! Thanks again for reading this long post!
