Tank #1 would have to be my redtip shark, although the Avocado Puffer keeps him in check Tank #2 would be my Parrot Cichlids Tank #3 would be my Green Spotted Puffer tank #4 would have to be my Red Earred Slider Turtle
my pleco is dominates my tank but the only aggressive fish i have with him are firemouths and they are really small(1.5in) so we shall see how things shape up
In my tank I've got a 15" or so FL gar, 8" senegal poly, 4 convicts, a big chocolate and big uaru. The boss? The uaru, no question.
Funny I have 2 sevs in a growout and the gold has a big growth edge on the green, but the green is definitely the boss for now at least. Eventually the gold is going to get wise and turn the tables I have a feeling. They're both SOB's though, I put in a pair of little jurupari and they killed them.
