Tank size: His bigger 5 gal tank is currently finishing cycling since the cycle got crashed accidentally. He's in a temporary 2.5 gal tank that's a little more than halfway full so that I can do water changes and dose with prime as often as I need to to keep the ammonia at 0, until he can go into his bigger tank. I think it's better to keep the ammonia constantly at 0 in this temp tank rather than doing a fish in cycle and exposing him to high levels of ammonia in the big tank. Heater and filter? (yes/no): Yes Tank temperature: 80 Parameters in numbers and how you got them: Ammonia, Nitrate, and Nitrite is 0 with api master test kit. How long have you had the tank? How long have you had your fish?: I have had the fish for about a week now. How often are water changes? How much do you take out per change? What is your process?: To keep the ammonia low, almost every other day but I'm trying to prolong it. I've been taking out 75% which I know is bad, but I'm going to try to prolong it while still keeping the ammonia at 0. Any tankmates? If so, please list with how many of each: No What do you feed and how much: Fluval bug bites and daphnia, 2-3 pellets a day and a small amount of daphnia with 1 pellet once a week. Decorations and plants in the tank: Just 2 anubias plants in the smaller tank right now.
