Had any problem with your CL bro towards your ray? are they now nipping on his tail? few weeks ago i had a problem with my CL(6schooling) they kept on nipping the stinger on my ray and actually taking the slime caot off,so i took the 6 CL and got a big CL about 7".
I will mike if i get my new camera hopefully soon. If you do the order i might also want a dip on a red seeing how big those red came in. DAYM! I hope all our fishes are champoins one day. We'll see. :D
I heard people dumping in ice cubes,i don't know if it is of any help in making the temp go down i have never tried it personally. Maybe try turning off the heater for a few hours that might help?
