I have 2 axeltols - 1 black, 1 gold. The gold is fine but the black one just wont eat!!!! We have even brought out schintelz slivers, tadpoles, fish chunks and worms. I know they sometimes don't eat too much in winter but it is summer here. Dad thought that could be the problem with the water being 23oC it might be too hot for them to eat. or that the water flow was too strong. Have you guys got any solutions cos we can't seem to slow the flow or cool the water much.
