Yes, they is.MN_Rebel;3944750; said:Isnt most exotics escaped from fish farms?

Flooding is the primary cause of the escape of farmed fish (in case anyone was wondering). There are many species that are only aquarium fish, so you are right; the fish farms can't bear all of the blame. There are plecos and armored catfish among others that have no food market value through out Florida. Each of these species represents countless events of released aquarium fish.
