The only reason they're in such smal ltanks is because they're gonna get bought by someone and removed from it. That is definitely not a permanent housing.Okay thanks for the replies guys. I pay this picasso tigger fish around 2 inches at the fish store that all their saltwater fishes are in 30 gallon longs. Just wanted something to pop? And ideas?
I don't understand why so few people are pointing out that 30 gallons is at least 100 gallons too small for most of the fish you're suggesting
