my angelfish has been acting weird ever since i bought him.he has been staying at the top of the water by the heater mostly and when i put in food i have to put it in right above his head for him to eat it.his fins seems to be clamped pointing up and facing the surface of the water.He was in a cycled 10G until i set up the 29G.since he was doing so poorly in the 10G i put him in the 29G and he seemed to move around a little bit more but he surely is not acting the way from when i bought him at the pet store.earlier when i posted about him everyone said he is just getting used to his new surrounding well its been about 4-5 days and he just sits there doing nothing.currently he is the only fish in the 29G and since he is the only fish in the 29G there is no ammonia,nitrite or nitrate but i did take some filter media and put it in there anyways.Any suggestions
