Tank Size Recommendations

  • We are currently upgrading MFK. thanks! -neo
Where are these numbers coming from?



Fleshy - you really should research Blacktips online. Then you would know the answer to that question. I can literally point to a dozen respected websites, as well as several shark books that basically give the same information about the Blacktip's maturing and maximum sizes.
 
Okay to help move this thread along - I'm going to present several species at once, in this post. Basically including my suggestions for the minimum tank size at maturity and full adult (large adult). Also I will include optium water temperature range for each species.

You bring me a nine foot limbatus, and Ill bite my own foot off.

In addition, seeing as how the record BTR only weighed 30#, I have a hard time seeing that fish being 6.5ft long.

Tanks should always be bigger than smaller, and I cant really say anything about your tank sizes. They will obviously work.

I just dont think that we should be providing this sort of information to hobbyists when their limbatus in captivity is never going to dream of touching nine feet.
 
I have to say that I don't think Kens black tip numbers are right for an 8 foot black tip. I think he was being way to generous on what a knuckle head hobbyist could get away with. I think Kens numbers would work for a 5 to 6 footer if it was brought up from a pup. I also feel that most hobbyist wouldn't be able to even get a black tip to their front door without the help of people that specialize in the transport of these animals. And lastly since most public aquariums have trouble keeping these sharks alive I highly doubt that most hobbyist could keep one alive for more than a couple of weeks let alone till its full size. I think a tank size for a 8 footer should be more like 100x60. Remember we are talking about a shark that behaves much like a spinner shark and breaches the water doing backfips on a regular basis. This is a super high strung shark that need LOTS of room.
 
At the shark exhibit at the Mandalay Bay, there are 3 or 4 6'+ black tip reefs, Fleshy.

Fleshy - you really need to Do The Research.

The Shedd Aquarium reports that 6ft BTRs weight about 100lbs(not 30)

And there are several sites like Fishbase.org & the Florida Museum of Natural History that state that BTR can reach 200cm (about 6.5ft).

As for the Blacktip (C.limbatus) reaching 9ft. I have no doubt - since in 2003 a 8ft 1inch, 190lbs Blacktip was caught in Texas*. *See the Texas saltwater Fishing Records . And the world record for Blacktip Shark (C.limbatus) was caught in Kenya, it was about 9ft long, and weighed about 270lbs. Remember I stated that Blacktips in the northeastern Atlantic tend to be smaller than in other parts of the world.

BTW - Josh - I agree that Blacktips (C.limbatus) aren't suited for private aquarists. As for my tank size suggestion - I'll just say that's the reason it's called a minimum tank size.

When I was at Underwater Adventures in the MOA, we had a group of BTRs all over 100 lbs and pushing the mid 5' to 6' mark.
