35 Gallon 20 inch deep fresh water aquarium Ideas?

The fish tank is 20inches high and 24 inches wide. 

I really don’t know what fish to get. I really just want fish that I would never get sick of looking at. 


If possible, I would also  like it to be very active

    I have two large goldfish about 5 inches each and a plecostomus. I enjoy them, they react to me, and they are easy to care for. By fav fish was a smaller fantail koi.

    I would recommend a canister filter though!


    For smaller fish the rule is 1 inch of fish per gallon.

    For larger fish use the rule of 1 inch to 2 gallons.

    * I have 10inches of large fish so I need 20 gallons, plus a plecostomus, so 25 gallons.

    By the way, I think you might be overstating the tank. You must take all 3 measurements (LxWxH)/231 - gallons

    If your tank is like mine (24x12x20)/231 = 25 gal
