What types of fish should I put in my tank ?

[I <3 my mutt]

I have a 29 gallon bio cube aquarium. I have a few Flame Tetras (I think that's what they are haha) and a few frogs. I was thinking a few platys or mollys but I am leaning towards Platy since Mollys can be nippy. Any other fish? I don't want any bottom dwelling fish such as Catfish or Plecos.

There are so many different kinds of fish out there... thats for you to decide. Personally I would get some schools of tetras and a gourami or two.

How about some nice sunset fire platies and a couple of white cloud minnows. Put 2 guppies in too!!

mollys get so big I would be worried about them perhaps nipping the frogs feet as they swim.

I would go with platys or endlers (both are smaller and more laid back)
Perhaps some mountain cloud minnows for something near the top.
Maybe some rasboras (I prefer harlequin - they have a more pinkish color)
Maybe a mystery snail for algae/clean up (these need two to tango, so you won't be over run).

Personal preference, check out what the pet store has (research ph, size, temp, ease of care before buying - don't always trust a sales person's advice)

Best of Luck!
