Hi Greg
I have a 20 gallon frag/display tank with larger rocks & rubble pieces from my 50 gallon pod filled sump, I'm looking for scooter blenny resident for it. His tank mates would be 2 snails, 2 hermits, tiny emerald type crab and 1 other non pod eating fish probably a chromis or damsel. I have a mandarian in my 90 and he gets all the pods cause he's the only pod eater in there, so I know how important pods are for gobies. So he would be the king and eat like one in that tank. Cheers Laurie
