it said blue gouramis could be kept with altum angels, angelfish, pearl gouramis, dwarf gouramis, croaking gouramis, bettas, kissing gouramis, sparkling gouramis, glass catfish (thats a disaster waiting to happen), and tiger barbs. blue gouramis would kill or fight with (in the kissing gourami's case) any other gouramis in the tank. blue gouramis are also to aggressive to be put with angels, especially altums. glass cats should not be put with any other aggressive fish for they are just to peacful, perhaps even to peacful for their own good. they often do not get enough to eat, and a blue gourami would terrorize them. it also said that they should be kept in groups, more males than females. another disaster waiting to happen. females can be as aggressive as males, and the males will fight over the females.
the figure 8 puffer compatability wasnt even finished, and it said that it should be kept in groups and with dwarf puffers. figure 8 puffers are prackish, and dwarf puffers are not.
the site also said that fancy goldfish were compatable with kuhli loaches, corydoras, upsidedown catfish, rosy barbs, otos, and tiger barbs. they are not compatable with any of those for they need different water temperatures. tiger barbs would rip them to shreds.
half of the compatability lists i looked up were half finished. not very reliable at all IMO
