I have a Black Shark in a 30 gallon tank. He is about 6 inches in length now. I know he will get large. I also see that he is shy, he stays in a cave all of the time. I am preparing to move him to a 75 gallon in the next 2 months. My question is is the 75 gallon large enough for him & can I add some Angle Fish?

black sharks can get very aggressive and very large. I know a guy that had one with other very large cichlids aggressive cichlids like red devils and buttikoferi. I believe he had trouble with the black shark being aggressive to those fish, so angels would definitely get harrassed or killed.

also, a 75 wouldn't be big enough for the black shark to grow to full size. I'm not exactly sure of the full grown adult size but I know it's very big. according to one profile I just checked out it's at least 2 feet.

i agree with jason, black sharks will not fit in home aquarias, and a 75 wont cut it.

How long will it take him to out grow a 75. I have a good spot in my living room & have already purchased the aquarium. I do have a room I plan to put a 150 - 200 gallon tank into a wall. But that will be a major construction project. It will probably happen at least a year from now. So my question is if I can hold him in the 75 until then? If not what to do with the fish? I am a relative beginner & was ignorant to the size the fish would become. The sales rep at Petco should have explained this to me or anyone else. I think she told me the fish would grow 12 - 18 inches. I do not really want to get rid of him as I have become attached to him.

it takes them a while to grow fullsize, so it should be okay to stick him in a 75g for a while

i believe the avg. size(in my mind) is about 24-36 inches range(of course varying) and i know my friend got his about 3 months and it turned from a 2 inch fish to a 8 inch fish in that time, so i am guessing that a 500 gallon tank would be best as this fish is a tankbuster and i would get the 125-200 fast.

I have no idea how quickly they grow but considering the huge adult size they probably grow fairly quickly. a 75 will probably work till the black shark gets to around 15" or so. at that time, if you still have made no progress on a larger tank (make sure it's at least 2 feet wide) then I'd try to find someone to take him from you.
