McTurtle Posted December 3, 2013 Report Share Posted December 3, 2013 I bought a 40 gallon last night and it came with fish. One is a silver tipped/ Columbian shark and I think he will need to be rehomed for sure as a 40 gallon just won't be big enough for him. There is also a humbug catfish, a rainbow shark, one green tiger barb, 5 neons, a pleco that I haven't ID'd yet and 2 other fish (one is probably a barb and the other may be a danio, but I have to take pictures and figure out what they are.) I'd like to have rainbow fish in this tank. I think maybe the neons can stay, but I'm not sure who else would be compatible. I feel bad for the lone green barb, so he either needs buddies or to find a new home. I'm not a huge fan of plecos and I'm afraid this guy is going to grow up and suck the slime coat off my fish or eat them. Is a 40 gallon big enough for rainbow fish? It will be planted. I'd like to have a few if they're happier schooling. I'm thinking maybe 5 rainbows, the neons (I might add to the 5 I currently have to a school of 8 or 10) and the humbug catfish. The substrate is currently smooth pebbles, but I'd like to put some eco-complete in eventually. Any ideas/ suggestions? Quote Link to comment Share on other sites More sharing options...
syno321 Posted December 3, 2013 Report Share Posted December 3, 2013 You will be fine with any of the dwarf rainbows, and, for that matter most any of the medium rainbows would be fine as well. Quote Link to comment Share on other sites More sharing options...
