I guess my question is...can a pleco live in brackish water? I have a violet goby and a pleco. I know the Goby needs to live in brackish water. I've read that some people say plecos can live in brackish water and some people say they can't. I would like to put the pleco in with my Goby so my question is, "can this plecos live in the same level of brackish water as my violet goby"? I know I would have to slowly acclimate him to brackish water before adding him to my Gobys tank - but would it even work? I have a 125 gal tank. The only thing in it at this time is the Goby. I may add some guppies back in later...much later...after a long - long quarantine for the guppies.
