Hi AZFRAG!! I am adding a sea hare into my 30g cube. I have never owned one, but I trying to make my cube great again. Any info that could help me would be greatly appreciate it. I have a fire shrimp, Melanarus wrass, Picasso Clown, and (don’t call the tang police on me!) a small yellow eye kole. There is a emerald crab some snails and some snails and red legged hermits in there as well. TIA!!
