I'll warn you now, bolivians aren't going to come greet you every time you walk up to the tank... Odd's are they won't do anything until you open the top up.
Doubt it... A standard 40 is 48"X12"X16" which is a similar problem to the 55. A breeder is 36"X18"X16" which is better IMO but that is a very large fish in a small water volume.oh ok would a 40 work? could tiger barbs go with the convict or is that over stocked?
