Thanks bf2king... that is important information to know!
You might want to check about the sharks then, too.... it is very possible they are banned as well. Also, just because a lfs sells it doesn't mean it's legal to keep it, so please double check. Around here alligators are banned in most cities, but there is one city who hasn't banned them yet. LFS's in that one city sell them, and then they end up in the homes in cities where they are banned. The fine for having one is over $500 and then the animal is confiscated, and most typically the authorities will euthenize it because they aren't prepared to handle it or keep it, and don't have anywhere to go with them. There are some places where any shark is banned... like around here! Our local ordinance says that if you get caught with a shark or ray, the fine is $500 for each day you have it in your possession, and beyond a certain length of time, or beyond a first offense, there is also jail time. The animals are then confiscated and destroyed. The disturbing part of this is that they are legal in our state... just not in our city!
120 will work for a shark egg, but after a few months the shark will need 125. 120 isn't long enough, doesn't have enough area for a shark to swim around in long term. Most of the shark eggs sold are banded cat sharks, and these guys can get about 41 inches in length full grown. They are nocturnal feeders and I have noticed a lot of people get bored with them early on because they're not very active. Main diet is shell fish... which can get quite expensive.
The banded catshark is actually a bamboo shark, Chiloscyllium punctatum. Something else to know about them is that while they hatch with the stripes which help to give them their common name, as they mature they lose the stripes and change color. Their adult color form is a bland gray.
It would be a good idea to do a lot of research about them before buying one. They have very specific needs and while they are one of the easier sharks to work with, any shark can be quite difficult to keep. The hardest part is in gettin them to eat once they've hatched. A newly hatched banded catshark will starve within a couple of wks if it doesn't eat, and they stress very easily. The hardest part about buying one already hatched is that the lfs's don't usually let you know if it is eating or not. A shark that is not eating within a week of having it is usually doomed. They also stress severely when moved/shipped... so even a shark that is eating at the lfs may not eat once you get it home.
Raising a healthy catshark will require a significant budget to keep it well fed. Shrimp, clams, squid... none of these things are cheap when you're feeding a 40+ inch shark! And watch the teeth when feeding. Feeding an adult shark can get dangerous if you're not careful. I have seen the damage done by small catsharks, under 12 inches... and it can be devastating.
Tell the boyfriend that I am also a fan of sharks and rays, but that doesn't always make them suitable pets.
This is a good book to get, written by Scott W. Michael. http://www.amazon.com/Aquarium-Shark...7588694&sr=1-2
I've read it cover to cover a few times, and its a good reference book to have on hand if you decide to try keeping a shark.
