small shark?

  • We are currently upgrading MFK. thanks! -neo
There are isolated populations located 100% in freshwater in South American lakes. Reproduction is a little different for them - with a shorter breeding period, but other than that, they are identical to the animals that move in and out of fresh.
 
yes i totaly agree with the migratory theary

Agreed - Brenden.

While - many aquarists that are into sharks - want to keep requiems. Very few are actually capable of doing so. Still the more "aquaria friendly" benthic species - such as catsharks, bamboos, eppies, & horns have a certain appeal to them. While these species tend to lack the "classic" shark shape of the requiems - each species has their own beauty & appeal. And the added fact that they can be kept in home aquaria.
Well there is a difference in my mind between a catshark and the one shown. I know that there are a lot of inexpiernced fish keepers that buy requeim sharks for a small tank. But if it were me, knowing what I know, I'd just setup a 180g for a fowlr and save for a shark pond to a least hold bamboos.
 
Well that would be best.

Personally I tend to feel that in private settings - sharks are better for being kept in ponds than in large home aquariums.

Since ponds generally have more swimming space to allow the shark a more natural setting.

Plus Home Aquariums are design for people - not the Fish.
 
Yeah - Chain Catsharks are cold deep water sharks - found of the Atlantic coast of North America. While they can be kept in captivity - the require systems with very powerful chillers. Since Chain Catsharks generally need water temps at about 55F(about 13C) or less.

Most Chillers for home Aquariums - generally only go down to about 60F (about 15.5C).
