Catshark

As of now I have a 75 gallon tank with a Blue Tang (approx 4 inches). It has a refugium containing live rock and chaeto. The tank is a year old to date. I plan on getting reef rock for the top but still enough space for the shark to swim. When the shark gets to big I plan on upgrading it to a 180 gallon tank. What are compatible fish to go with it?

 

a catshark? interesting..... definitely gonna follow along.....

 

I think a shark isn't the best idea and they should be left to experts. First, they need a ton of room to swim which a 75 doesn't allow and they need a very fine grained substrate and plenty of open space. They also require perfect parameters and they need to be kept stable. They are overall very hard to keep and I don't know if you have enough experience to properly keep one. Even newly born sharks are about 4" long and grow relatively quickly. They can get up to 2' in the home aquarium. There are many different species of cat shark, the most common being the Coral catshark. Either way, they can be very aggressive and can and will eat other tank mates, even if they are larger so I wouldn't recommend any other fish to keep with them unless they are feeder fish. I don't want to burst your bubble, but I don't think with your setup, a cat shark is appropriate.

 

You can't keep a shark in a 75, Sharks need to swim or else they will die. How do you know you will get a 180g?, **** happens.

 

oh yeah thats right; if sharks dont swim then they die just like that; i think its to gather oxygen or something

 

A little coarse but I agree.

 

Not with this type of shark. I have one who mostly hangs with my eel in the sand and rarely swims around until the evening. Very much agreed that a shark should not be in your current size tank, WAY too small. When you actually purchase your 180 then get one. Their care is actually very easy. Mine LOVES squid!

 

Yes hate to say it but I agree. Im not a fan of getting a fish to big for your current tank with the intention of upgrading. A lot can go wrong and you may not get the tank. Get the proper size tank first then buy the live stock. Not just nagging on you, I see a lot of people saying this for tangs and other fish.

 

Only a few sharks are evolved in such a way as to require constant movement to breathe; they're the minority.

 

IME catsharks as they get larger they begin to swim incessantly in circles, in all but very large tanks, greater than 200 + gallons. I believe because they are pelagic creatures (open ocean) the confines of the average home aquarium does not meet their space requirements.
