Hey, I know that guy!
Likely story :lol:
It a nice huge tank but imo those black tips are too big for it. I don't have a ton of experience with ORVs so Maybe zoodiver will chime in, but the multiple half flips of the tails and the jerky movements in the swim pattern tell me that they a utilizing extra of energy navigating the width of the tank.
Can someone with first hand knowledge tell me how large a California horn shark will get? I have read several books now and they all say something different and honestly it's kind of irritating. One book says 40" but then has a disclaimer that most don't get over 30-33" another book claims closer to 48" is max with most getting about 40-42". Such conflicting information out there and it seems that there are only a few active members here that keep sharks or have any knowledge about them. I just recently went to the public aquarium near me and the had 3 port Jackson sharks roughly 2ft each I. A tank that couldn't of been over 200g. I realize they have the knowledge and space to move the sharks when need be but it surprised me to see 3 in what I would consider a small tank.
Depends. The reason for the variation in sizes is due to the range of locations you can find them (temp range). It is very typical of horn sharks that you find in a range of temps. Port Jacksons get much bigger than most think. They can get into the 5 foot range. Cali horns will be 2 1/2 - 3 1/2 ft in most cases.
And sad to say, some aquariums aren't great examples of shark husbandry.
