Is 90 gallons the minimum size tank it should be kept in? When he's fully grown I meant. And how big should he get when he's fully grown? Interested in getting one myself, and saw one at the lfs the other day. Sure it's the same L number and all.
The information is limited on this fish, but it is suspected to get to around eight inches, so use your best judgement... no fish wants to be a sailboat in a bottle.
