I recently picked up a 33 gallon long, 48x12x12 and was wondering what anyone would recommend for it. It will be a planted tank and was thinking about doing a large school of tiger barbs but I already have a 20 gallon long with some corydoras and cardinal tetras. I was wondering if there was a singular or pair of fish that would fill the tank out or maybe something like a couple Pictus catfish any ideas are welcome
33 is a very good size. People collect them around here, they get bought up as soon as they pop up. I have one myself.
My go to suggestion would be a pair of one of the smaller amatitlania (Rio mongo/claro convicts, HRPs, nanolutea, kanna). The length also makes it a good stream tank, in case you want to try US native minnows or darters or something. Of course these both don't involve plants, so if you're set on plants, you could do a pair of laetacara, Bolivian rams, anomalochromis, or any of the krib species. I recommend taeniatus for the latter, if you can find them. Don't do apistos, ivanacara, or blue rams, though apistogramma nijessini/panduro are exceptions. Dicrossus are also nice. With a four foot tank you might be able to get away with a pair of dwarf pikes, but don't quote me on that.
