Biggest fish for a 10 gallon??

[Agent_Scully]

OK. Just out of curiosity...what is the largest fish you can comfortably and happily fit (by it self) in a standard 10 gallon tank?

Freshwater and Tropical or Coldwatered species are accepted.

I prefer single fish tanks. Its easier to make sure each fish gets everything it needs.

and I don't want it too be "well...you could maybe fit a _______ in there but not easily. I'd like the fish to be really happy but not like neon tetra size.

Probably a betta or a mid-sized gourami. Most other fish that size are too active to be comfortable in a 10.

A Betta would be happy in a 10g.

Aside from that nothing big, anything I would suggest would stay under a couple inches.

As far as ONE "big" fish for a 10, I'd probably say Dwarf Gourami, Betta, Swordtail, etc.

Coolness. Any ideas about some uncommon fish I could try?

Coupla large Sailfin mollies? or one REALLY nice male?

 

[nguyendetecting]

if looking for a "uncommon" fish try the bumble goby, be sure which one you're look at though most of them are brackish water. Still pretty cool fish IMO

Could I do a male and female sailfin molly or would they kill each other? Or two dwarf gouramis?

 

[luckydud13]

male and female molly will be fine but be prepared for fry! And idk bout the gouramis

Only one gourami for a tank so small.
