I have recently set up a 72x15x24 saltwater tank for a friend of mine.I was wondering on the keeping of shark purses.Does anybody have any knowledge of these fine specimens.the tank is ready to go and been maturing for a good few weeks now.all the levels are correct. I NEED AS MUCH INFORMATION AS I CAN PLEASE.
:thanks:

Well, they're fairly straight forward, you just let them sit in the tank until they mature and hatch. (They take around 3 - 6 weeks to hatch
However they need a cycled tank (running WITH fish for over a month, month and a half) It's a common mistake to assume that 'cycled' means having the water sitting for a few weeks, and then adding all your cool fish, however, because there's no fish in there, there's no waste being produced, so as soon as you add fish, your tank will begin the cycle of adjusting and stabilizing. Now I am not too sure with the shark eggs, because technically there isn't any waste being produced, but it's still wise to add any fish to a cycled tank.
With the shark eggs, the pups (babies) will start off their size at around 4 - 6 inches in length, and depending on the shark, will just stick to the bottom and not really swim around. I have raised banded bamboo sharks, and as like ANY saltwater shark, they will get over 3 feet in length.
As for feeding, they are tough to feed and often need you to wiggle a feeder minnow in front of their nose. Also after hatching, and depending on how many purses/eggs you have in the tank, you need to consider SPACE. These fish grow fast, and need a decent amount of room. I would also consider what you're going to do with the sharks after they hatch? Most aquariums/pet stores dont have the capacity to keep them when they're full grown.
Overall i'd recommend the banded cat shark, they get up to 40 inches and are the smallest of the saltwater sharks, and need a minimum 130 gallon tank
i'll add more when I have time..
I have to agree with everything vTEC commented on.
Shark eggs are really cool to watch grow and then hatch from a embryo to a juvenile fish. Its absolutely facinating to see them progress.
Sharks are kinda tough critters and are pretty sensitive to the water conditions a well. The smaller species can be done but its a challenge. It will require a very large tank and a stupendous filtration system. While the minimum tank size is 130 gallons a tank considerably larger is best. They are best done in FOWLR tanks that have modest lighting set ups for the best veiwing oppertunities.
