Hey guys and gals. I am thinking of getting some fantastica soon and I was wondering which ratio is better. A 2.1 or 1.2 or a 2.2? I know there might be male/male aggression but which is worse, female/female/ or male/male aggression?
Thanks
-Alex

In my experience, 1.1 works best, followed by 2.2 if the tank is big enough. Males are somewhat aggressive towards one another but should be ok if you give them enough space and plenty of cover.

I hit submit too quickly - when I kept them in groups there was also some aggression among my females; I prefer pairs in 12x12x18 tanks over groups in larger tanks (30 gallons and up) but the latter should work as well.

i keep a 2.1 trio in an 18 vert that works pretty well. ive heard pairs are better for breeding however.

my 1.2 was great a few years ago in a 25 tall. They laid eggs weekly.

I have 0.0.4 group ATM that are going in a 47 column next week. Then i will be able to watch them and sex them out, however with that much space they should all be able to select their own territories i hope.....
