If your in a legal area id get one. Rainbows stay on the smaller side of snakeheads so a 60-75 should be fine for one. Tankmates are iffy as it is a predator with the ablity to kill fish larger than it self to take that into consideration when choosing tankmates. Also i rainbows are very beautiful so id try to get it on a diet of prawns and cut up white fish or smelt rather than live feeders.
