Is a knife fish compatible in my tank??? - Aquarium Advice

10-05-2005, 04:53 PM

i saw a knife fish at Petco while i was shopping today and i was wondering if they are compatible with all the fish in my tank.. they are on sail for the next two weeks so i have some time to think about it. They had it labeled "Clown Knife fish"

The main fish im worried about is my rainbow shark becuase my shark likes to hide in tunnels and stuff and i know knife fish like to as well. would that be a problem? And what about all the other fish in my signanture?

One more thing... don't worry about the size the fish get, im getting a new tank, probably at least 100 gallon for a gradutaion present

no, even if you have a 100 gallon tank. 180 gallon MINIMUM at the least. They get about 36 inches plus for most of them.

Actually, you do need to worry about fish size on this one....he will eventually hit 3'-4' (too big for anything short of a 500G) and grows very quickly to 18" when kept under good conditions (and at 15" can eat a 4" African cichlid).

awesome.. thanks for the info.. i thought they got about 2 feet

Toirtis · 10-05-2005, 05:05 PM

Even at two feet, they would eat every other fish you have in very short order.

right, point taken.. [acronym:e728189bd3="Laughing out loud"]LOL[/acronym:e728189bd3].. i wont get one, i just thought they were neat looking. If im going to get a 300 gallon tank im going to get an OSCAR

It is unfortunate, because they are really cool as they get bigger...lots of personality, too.

if you had them in a 300 gallon tank say, is there any tankmates you could have with them? Becuase i really want to get an oscar one day and i know they need a big tank and are very intellegent fish.. well mostly my husband wants the oscar.. lol.

A large (14"+) oscar would likely be safe, yes.

but would they thrive together? Say i got the tank and bought them both fairly small... 4-5" would they grow together and be happy?
