I now have moved my giant gourami in his own 360 gallons tank. It's an 8x3x2 with a 120 gallons sump. I have put in him a few Asian fish: tinfoil barbs, denisonii barbs, clown loaches, tiger loaches and a dwarf gourami. Any more suggestions on other small Asian fish I can keep with him? The tank has a pool filter sand substrate with a few driftwood and scattered rocks. Minimalist as it is.
