Thank you. I'll raise it to 80 which is a tad warm for the geo gold dust; but otherwise fine. If i can catch them (ha ha); i'll move them to the discus tank (there are 2 left) - the tnak is 8ftx4ftx2ft so not trivial to catch a fish that doesn't wnat to be caught.
I mentioned that i think 2 of my L172a are sitll alive; well this evening i looked into the hole of one of them and saw both down there and a partially empty mystery snail shell so i guess they found something to eat ?
