Sharks and magnesium

[killemall]

The local fish store is telling me that low magnesium may make sharks not eat and starve to death. Does anyone know about this? Thanks

Mg is important for digestion, so low mg could in sense show up like you've indicated. Keeping reef level mg is all you have to do, easy to test and dose, and it is very stable so it just something you need to do infrequently. Fish do absorb elements from the water column, not a bad idea to also keep reef level ca.

Thank you. My 16 fish and eel are fine. It's only my shark who don't eat and starve to death.

The LFS told me sharks need it more than fish. Anyone know if this is true

I have already bought a tester. Just don't want to open box and return if you guys say the shark magnesium thing is bullcrap

Some fish are going to be more sensitive to a mg defiencency than others. The fish I keep, lions, scorps, anglers, eels have been affected with digestive issue that a higher level of mg has addressed. Other fish will not show the same signs. I keep mg in my predator tanks at 1400ppm. Other reasons to not eat can be other nutritional defiencencies as well, as well as thiaminese poisoning due to feeding foods high in thiaminese like krill and shrimp.

What kind of sharks can your distributor get besides the Epaulettes?

Too many to list. I’ve been importing for 30 plus years from all over the world. I’ve handled sharks and other large animals for public aquariums as well so I’ve seen a lot. Tank size matters

Okay... In that case if there is too many to list then I will narrow it down. What sharks can your distributor get in the 2'-3' range besides, Coral Catsharks, Marbled Catsharks, Brown Banded Catsharks, Grey Bamboo Sharks, White Spotted Bamboo Sharks, or any Horn/Bullhead Sharks?

I was looking for a true Brown Smooth Hound for a while but didn't have any luck. I'll shoot ya a message since we already kinda hijacked this post. All those are large sharks that can get 5' or larger.

Oh wow. I had no idea about this. My shark is such a little piggies though. Always munching on the LRS I give her.
