I am starting to think about my next tank. It will be at least 90 gallons. I like severums. Are they good with tiger barbs? or do they get big enough to eat them? If they work with tiger barbs can you suggest some other tank mates. If severums do not work with tiger barbs could you tell me some cichlids that do? (I have heard of tiger barbs being dithers in some tanks) I am not sure of the set up yet--but thinking sand and gravel, driftwood, some live plants but not heavily planted. Thanks.
