Ideas for a 125 gallon tank

I did my 125 as a river tank for hillstreams and gobies a year or two back. I'm thinkin' about goin' native with it. I've been seein' some beautiful wild sailfin mollies, pupfish and pigmy perch lately with all the rain. Gotta get rid of current inhabitants first.

If I were setting up a 125 for freshwater I would either do Discus or as you said a bunch of small tropicals and it would be planted, I think a big tank with lots of small fish could be pretty interesting. Other randoms for that size tank i might consider, datnoids, fahaka puffer, BGK.

definitely planted with some nice roots/wood, a couple of big schools of little fish plus a school of a bottom crew (cories, loaches, etc) plus a few "stars" (festivums, Aequidens ,gouramis etc.)

You could do South American with tetras, cories and the above mentioned cichlids OR SE Asia with rasboras, barbs, dainos, loaches and gouramis. You could probably do a west African tank too with riverine kribs, riverine synodontis and various African tetras (ie congo)

What about some Rainbow fish? That size tank would be awesome for some of the larger bodied sizes.

A 125 would make a great rainbow tank. It'd also hold a decent-sized school of Congo tetras.

When I had discus in my 125, I had 3 schools of different schoolies; 25 green fire tetras, 20 rasbora hets and 30 cardinal tetras. The three schools moving independently made quite a sight.
