looking for 36" long tank around 60ish gallons. red deer

You should be looking for a 50 gallon tank 36x18x18. I am doing exactly what your doing and upgrading to one. I was going to go for a 40G breeder but was talked into picking up the 50G for the extra depth.

I think it makes an awesome tank - enough water for stability, enough room for a variety of fish, and it wont break the bank stocking and setting it up.
