I bought two bettas yesterday afternoon, (both are females). They seem to get along pretty well and they live in a one gallon tank. (I am unable to buy any tanks that are any bigger, right now.)
The temperature is fine, but I'm not sure about pH, nitrite, ammonia, etc (and I can't test that anytime soon either)
I haven't done any water changes yet.
So here is my problem- one of my fish is TOTALLY fine and swimming everywhere and eating and being happy. The other one spends most of its time at the bottom of the tank, not eating or anything. However, it reacts well to any stimulus (the net, the other fish, etc) but won't eat (I've only fed them about once, now, though). It usually only comes up to the top for some air. Should I just wait to see what happens with it? (Externally, it doesn't appear to look any differently than when I bought it.)
