SAE very sensitive water parameter. High PH will kill it. First it will stop eating...and jsut like your CAE... then die.

All my SAE kicking in PH 6.2. They do eat well. living well. So, they grow fast and fat.

Ai ya..the clown loach. i kept one before. just in my planted tank alone with the rest of tetra. it will kicking like gila. grow fast... till 4inch n I gave away. (I am u can keep just only 1 clown loach or any loach with other fish.) Who will just keep a loach in a tank?
