I have 5 females on my 10G, I know it was suppose to be 4 (2.5 per betta) but the last one was SOOO tiny and the females were on the same tank with a male (don't ask) so I got scared she would die on that tank alone with the male, besides, I was watching her on the LFS for like 2-3 weeks and she never grew, I thought she was like a betta-dwarf, been 3 days and she is like 1.3x bigger than when I got her.. >_>!
But yeah, I would totally overstock (even more) with the 2-3 guppies, I want something like snails or shrimps xD! Snails are so awesome but they are dying on me, idk why, the shrimps are fine, just the snails, they grew alot and now are dying, after the 2nd month or something... :C! Maybe their metabolism with me are way too fast (no joking) so I want to avoid the snails, maybe my tap water have some chemical that are deadly to them :C
And I'm way going away from the original topic.. Sorry!! But yeah I love how guppies looks like, they are like mini-bettas which are social aaand with rainbow colours.. lol! XD
That's me on the photo alright.
