Tankmates

the nurses grow to like 3m (10ft), so no. and wobbegongs are known to eat everything that moves (i.e your coral cat) the Brown-banded Bamboo is your best bet for a friend for your coral. altho a member on another forum recently had one of his Bamboo pups kill a coral cat pup.

How big is your tank? if you can find them Arabian Bamboo, White spot bamboos, Marble catsharks and Papuan epaulettes could all be suitable tankmates

What kind of wobby is it? That makes a big difference

Also how big is the tank you have??

Wobbies range from 3ft to 10ft depending on species.

Nurse shark way too big.

Banded are a little bigger but likely ok depending on your tank size. Certainly the best choice of the 3.

All of the sharks you are looking at are unfortunately are not suited for a 180.

If by red spotted catshark, you mean the Chilean cat (Schroederichthys chilensis), they are a cooler water species. They are also not a commonly kept shark due to be very difficult to maintain in a tank setting. I think your sales guy cares more about getting your money than what sharks are good for you.

I'll be honest I've kept coral catsharks in a 180 gallon tank before and your best bet for tankmates is probably some chromis or damsels. They don't compete for food and they don't pose a threat to the shark. Also they don't place a heavy strain on the filtration and could substitute as food.
