Hi. I bought 2 axies last saturday and put them in a tank I set up just an hour b4. I used tap water with an aquarium conditioner called prime. They eat bloodworms once or twice a day. I vacume the sand flooring each day and they seem to either be different on personality or maybe one is sick. My wild type (Aristotle) is chill and mellow and eats but not as aggressively as my leucistic (Apricot). Apticot is going crazy in the tank right now. Swiming quickly back and forth. I just came home so I don't know if she is doing it because I am near the tank or if he/she is stressed. She has a ferocious appetite and she is only swiming back and front where I am in front of the tank. What does this mean?? Do they have varying temperaments?? Also I have never done a ph test and change water 20% daily in 10 gallon filtered tank.
