im pretty knowledgable about keeping saltwater fish.. i have a really nice reef tank and i recently set up a 180 gallon oceanic. and i have a grouper and a clown trigger.. im wanting to get either a banded cat,coral cat,or marbled cat shark.. which one would be best for my tank... i see most websites say all 3 ca be kept in a 180 but im seeing the marbled and the coral cat are a lil smaller that the banded... are they really hard to get to eat??
 
I dont know saltwater well, but im fairly sure a 180 is not big enough for any of those for life. But we'll wait until someone who knows chimes in.
 
I have never kept a marine tank, but i have volunteered in a zoo that keeps these kind of sharks. You are looking at animals that get over 2 feet long, and a standard 180 is only 2 feet wide, so that should be a good indicator that the tank is not big enough. I have seen young sharks kept in 90's for quaratine, and they were definitely cramped, and this was at just 12" or so. double the length, multiply the mass by 8 or so, and you have a shark that needs a tank much larger than 180 gallons.

Other people on this site are far more knowledgeable, but the minimumn for a shark for life would be an 8 by 4 footprint, in my opinion. Sharks are large animals and need space.
 
180 is kinda tight for most sharks. Coral catshark or marbled catshark would work for awhile, but I'd suggest upgrading at some point.
 
im gonna upgrade eventually.. like i said most websites say catsharks can go in a 180.. most ive researched about rarely excede 24'' in captivity
 
The problem is most online sites that sell sharks - often quote from an inaccurate source. So they get the tank sizes all wrong for sharks.

Try looking on Youtube sometime - at people who have a 3 ft shark in a 300 gallon aquarium. It looks very cruel to the shark - as the poor shark can barely turn around.

The easiest types of sharks to keep - tend to be the Bamboos, Epaulettes, & Coral Catsharks. Still for these types of sharks - you will eventually need a tank that is at least 360-750 gallons (depending on the species).
 
yeah, so a standard 180g is too small [for life] for the smallest available species. you will need something wider.
you should also know that clown triggers are terrible tankmates for sharks.
