Yet another stocking question

[colinsk]

I think i have found a free 90 gallon aquarium for free. It is 48" long by 24" thick and 18" deep. I am thinking of only filling it partially and using 3" of substrate (all for plant reasons). This will leave a heavily planted section that is about 12" deep. This makes it about 50 to 60 gallons. I like gentle friendly fish. I also like schooling behaviour so I am wondering what choices I have.

I will certainly get a school of Sterbii corys and lots of Amano shrimp. All of my fish are very small, the largest are Lemon Tetras so I am thinking of something larger. I have been thinking of 6 boesemani rainbow fish but I don't really know anything about them except I can get them locally and they are pretty and within my small budget. I am a little overstocked with Lemon tetras and they continue to breed so I also would like to move a school to the new aquarium.

What other fish can I think about? Remember that the tank will be overrun in plants.

Here is a picture of my 29 gallon before it was as overgrown as it is now.

See my signature. All my fish are schoolers (except the angels).

Just a personal opinion, but I really like black widow tetras and white diamond tetras. They are cheap and easy to care for. They grow bigger than the little tetras and I like this combination because the school is black and white. They are similarly shaped so it's pretty striking having that contrast. You can even get long fin ones as well. My biggest one would be about an inch long. They love plants too.
Hope this helps!
