I have 3 german blue rams @tm. 2 I believe r paired and giving the other a hard time so I plan to get a few more. Maybe 2 or 3 more. My 30 gallon in the living room is just a little loud (filter noise, water splashing, etc..) anyways those fluval edge aquariums would match the style of my living room nicely. My question is. How many of these little guys can I put in the fluval edge 6 gallon. Planted some, few rocks, make it more like there natural enviroment. I know 6 gallons is weak and not a MFK size tank but it is what it is. Thanks. Verruckt...
