I have 3 pink kissing gouramis and 2 opaline gouramis, all but one are juveniles the biggest of these about 6cm, one kisser is about 15 cm. They are currently in a 105l tank (while still small) My question is can I keep shrimp (probably fan shrimp that grow to approx 10cm) with gouramis? Also when I get a bigger tank (considering a huge 6ft tank at the moment) can I keep a small school of glass catfish with them? (maybe 6?) Thanks.
