Hi, I cleaned my turtles' tank today, as I've done a couple of times since I got them...
When I finished, I put the guppies and the turtles back in the tank... there were about 7 guppies left. A couple got eaten and the rest just DIED within a couple of hours... what could've killed them??
I'm afraid they might be the "canaries in the mine" and something could happen to Cheech & Chong... they seem fine though...
Any suggestions?
