Ive never had a brackish tank and was wondering if it would be possible to establish one with a 10 gallon. Can anyone suggest some fish i can keep in there?
I did a lot of looking into this... you CAN set up a 10 gallon brackish tank, but you are really limited in terms of fish selection.
the most viable candidates are bumble bee gobies, indian glass fish, and guppies... you can also get a crab... and if acclimated properly, amano shrimp will do fine in brackish water. there is more discussion here: http://www.aquariacentral.com/forums/showthread.php?t=120149
i have a 10 gallon with a crab, guppies, ghost shrimp and its what i started my GSP in... he was only there for a month when he was tiny and now he has a 30 with the same combo. he sometimes eats the guppie babies and his new crab friends.
