Well I started a Sorority tank last night. It is a 29 gallon and I bought two "tree"-like decorations and tons of fake plants(I have neve rhad success with real ones). I bought 7 of them for the tank and ti is true, it seems the darker colored Bettas(one is dark red the other black, blue in the light) are more hostile. The black/blue one will chace the others away if they get too close to her. So far, 24 hours, no torn fins which has to be a semi-good sign. I am only having problems with one tha tmight have swimbladder disorder which is nothing major. I also need to rig the pump to have less of a stream. Right now when they get close to it they are pushed away to the otherside of the tank
I have had a single male betta in a 10 gallon for a few months now. I am not new to fish but new to Bettas(I was always unde rthe assumption they livved in a small container, some in those horrible plant/root eating containers) so never considered them. Now both of my tanks are full of them
So far I love the sorrority because they are very active and they do seem to have their own personalities compared to other fish. I mostly love that I set the tank up in my foyer so when you walk in you have this nice big tank.
The light on the tank blew out and I am buying a new one tonight so once that is set up I will take some pictures!
