i think you can put in like 3 endler livebearers or white clouds.
what kind of tank is it? the minibow 5 made by aga? you can change the stock bulb and put some more wattage in there if it is. then you can have a nano planted tank with lots of shrimp.
What about tiger barbs?? I know they don't get very big and you could probably have a couple in there. Maybe dwarf platies??
I just have a betta in mine. He does really well in it. Because bettas breathe air you don't have to go to all the expense of getting an air pump, air line, etc. He currently has a columbian ramshorn snail buddy who keeps the place tidy. Bettas have alot of personality. Mine know me by sight and will come up to the surface to "greet" me and see if I have any treats for him.
Tiger barbs??? :22_yikes: They almost get to 3" and are a shoaling fish which should be kept in large groups. As far as "dwarf" platies go...I've never seen any proof that such a species exists.
Now I coulda sworn on here I read someone looking for "nano" fish aka fish for a small tank and someone suggested tiger barbs. I myself have a dwarf platy. I don't know if it is a freak of nature thing or what but her and her other siblings have never gotten over 1 1/2 inch long and all my other platies are 2 - 3 inches. My suburst platy could be pushing 4inches LOL. I dunno I have never measured her, but she is huge.
