Monster fish noob, upgrading tank

[voiceinthedesert]

First post, excited to read all the info on here. I bought a black ghost knife a year our so ago and he's outgrown the 50 gallon I have him in. I want to move him to a larger tank and was considering tank mates. I have always loved giant gouramis, but not had a tank large enough. If I get a 100 or so, can I put the ghost knife in there with him? I understand that I'd have to upgrade to a little larger at some point, but was hoping it will work for a year or so until I get out of my apartment and into a house.

Does that sound ok? If not, what size wither you think is the minimum for that amount of time? Other suggestions on tankmates for a ghost knife are also welcome

Should clarify that I'm looking specifically at Red Tail Giant Gouramis since they seem to be smaller and less aggressive from what I've read.

Clown Knives generally grow to 24"+ in captivity.. a 30" wide tank is a start.. 100 gallons is just too small for a RTGG or a CK. How big is your CK anyway?

He's a Ghost Knife, not a Clown. Should only get to about 18 inches as far as I know. He's only about 8 inches right now (been a very slow grower despite me feeding him quite a bit), spends most of the day in his little log and ventures out by night.

good tank mates would be standard community fish!! i ha ve mine with my large angels and clown loaches also silver dollars! i have a giant gourami in a 92g or 350L tank and he loves it!!

Crap.. Sorry about that. Yeah 100gallons is still too small for a Ghost knife. Just save yourself the trouble and upgrade to the biggest you can possible instead of upgrading every few months.

you need to get atleast a 180g. The 24in wide footprint is a good START for monsters. And its a pretty common tank and wont break the bank.
