Hi,
Well I must say that these guys really like deep sand beds and really no direct flow. And then also very little flow after that.
Is it just me or the picture, but is the tank evenly lite. The conor he is in looks darker than the rest of the tank. Mine like pretty bright light and my sand beds run from 4 to 6 inches. I run 2 mp40 mounted on the back wall of a 30 inch wide tank. They are running on the lowest setting possible.
Only 1 of my 7 has ever moved and he was sick. Since his stay in the QT tank and return to the DT, he has not moved. Yes there are always other ways, but this setup has really worked for me.
I don't want to sound off, but I feel these guys really need a certain type of tank setup to THRIVE, not just hang in there. off my soapbox now
Either way, if he is moving, He is not happy at all
Good luck
