My tank is a 75g reef ready, and about the guppies I just went with what the lrs was feeding him I can still swap foods, so should I cut up a silversides instead of feeding guppies? How about fresh muscles? I rather lose shrimp than a tang lol I plan to get a small school of yellow tail damsel maybe 5-7 and he can eat those if I go to long without feeding him. They're $3 fish, I just got 3/8" thick glass lids cut for my tank and they're within an 1/8" of the plastic edging I almost cant lift them up off the tank its a snug fit, and a heavy piece of glass plus my taos are sitting on top of them plus im building a completely enclosed canopy for my tank so I think I got the escaping thing down. What am I missing?
