GET THE KRIBS!!!!! I have two females in my 55 gallon planted community tank, and the only fish they bother are each other!!!
I researched them before I got them and apparently the only problem they have in community tanks is if you have a pair, then they will breed in wet cotton... unfortunately excluding the other fish into a corner of the tank. Otherwise, they couldn't be better!!
The kribs colors are SO pretty, and the females are prettier than the males!!
To sex- females are smaller, have a rounded tail(with no point) are usually more colorful
males are bigger, duller, and have a point on their tail.
And most of all, Sasha, the Krib's personality rules all. They are beyond cute!!!
Enjoy!!!
