i know that my water temperature is too high for an axolotl, the water temperature he is average about 26 celcius, that guy which are floating is eating well, he sometime float and some time at the bottom as usuall, i actually hand feed them and as usual, when they see me back home they will suddenly go at the water surface searching for worm, i do regular water change every week is that can cause the water to be bad for them??? or it is the sign of heat stress?? should i put them in the fridge for a while if that is the sign of heat stress and the fridge question, should i closed the fridge door if i put them in there, can he breath if i closed the door??,and btw, that rock are very large, even it is actually larger than adult axolotl head, if you mean that sand, yeah, i already put it out....heeeee.. i dont really see any sign of stress cause these guy are very active and eating very well, thier body dosent sign any stress accur, im really puzzle.... :dizzy::dizzy:
