Hi, I have a betta in a cycled 2.5 minibow tank. He is lethargic, He will swim around for a few minutes but then stay in his cave or a silk plant for a good 10 minutes. The tank is heated to 78 F, the temperature doesn't fluctuate (I have a noe-therm 25w heater) and a thermometer. I change 20% water three times a week, and I have a turkey baster to suck out uneaten food and waste. My room is bright so he saw his own reflection in the tank, I darkened the room. However I don't think his reflection is stressing him out because even in a dI'm room where he can't see his reflection, he is still lethargic (Although it is possible he could be seeing his reflection, I can't say with 100% what he sees). I found a way to lessen the flow of the filter, because those filters are often way to strong. It gives enough current to let water flow over cycled media, but not enough to make a big current in the tank. He'll swim around a little more in the morning, and will eat readily. He doesn't have stress strips nor does he have clapped fin. However I know that betta's natural behavior is not to sit around for long periods at a time and then briefly swim around. There is 0ppm NH3, 0ppm NO2, and 10 ppm NO3. He is a half moon tale, so I expect him to rest more then smaller fined betta, but still I don't think he be so exhausted after 2-5 minutes of swimming. I got him about a week ago, so maybe he is still adjusting to his new home, but I don't want to be an irresponsible owner and assume everything is fine. My problem is I can think fo several reason why he is lethargic, but can't tell one way or the other which (if any) is the problem. Thanks
Update:
He actually seems to be a bit more active now, but he still doesn't seem as energetic as I think he is supposed to (I'm new to the hobby, so I only know descriptions from research on how these fish behave).
