I think convicts are a great choice they are great to watch and hardy enough to stand up to most fish if needed. I have a blue Acara which is a fantastic tank mate. Dollars are great unless you have a planted aquarium.
Would a oscar,Jack dempsy and some geo's work in a 150 gal tank. Maybe a rope fish and a plec. Your ideas would be appreciated. I'm aware that the first two can be aggressive. But is there enough room to give them space.
Same. Some times I don't see mine for days except for feeds and then it's like it owns the tank. Been like it for for a year. When ever I'm moving rocks or cleaning he comes up and wraps and rubs up against my fingers etc. Great fish.
