all those animals are mine.. cali ray and grey bamboo shark.. IMO no nurse shark should be kept in any aquarium unless it is 10,000 gallons+ and evan thats small for a nurse!
i havent had too good of luck with sharks ive had two - the first i bought for $50 from lfs it was a baby banded cat and the second was a banded cat egg and lasted a bout 2.5 weeks i love those things there soo fasinating. and i with i had a bigger tank too. i have only two 55 gallons. how big was the shark you saw?
yah that is cruel they should just let it go in the wild. the one i saw was only like a 12" it was in a 125 but that even cruel because they just grow soo fast.
i have a 205 now but my 300 will be here next week , then my 500 will go up late this summer
the grey bamboo reaches a max of 28 inches..but good luck finding one, their pretty rare in the aquarium trade, im lucky i got one
