We have brought a new tank and when we put our 4 Danios in it we didnt have a heater.... they were swimming around middle of tank and chasing each other and in our experience (which is beginners) they looked fine. NOW we have put a heater in their as we was going to get some Neons too and they all just seem to be at the very top of the tank opening and shutting there mouths and not doing much at all.
My husband set heater yesterday at 22 and now he has turned it down to 21, and usually when we feed them they go mad but this AM they dont seem bothered.... what should we do?
