Weird Columbian catshark behaviour? Can someone help?

stray current? Ok...any tips on how to fix this? He was sold to me as a salt water catshark, and was living in a salt water tank when I got him from store...

 

The electrical equipment we put in our tanks are designed to be waterproof, but sometimes things don't get sealed up all the way and allows a little bit of electrical current to enter the water. This can sometimes kill or only bother fish and coral. the best way to fix it is to unplug one item at a time and see if it makes a change. In your case it would most likely be your heater since it is where the fish is going. You could also use a multi-meter to test for voltage in the water.

 

Can you post a pic of the shark in your tank. I'd like to see the shark in the tank.

 

"and may also be acclimated slowly into a saltwater aquarium"

Was he slowly introduced to the tank? If the tank is housing anemones, I have to believe that your salinity is in the 1.022-1.027 range, correct?

If so, your shark may simply be struggling to acclimate.

 

Ahhh that's what I think.

 

Ok here's a shot of him. I unpluggged heater and plugged in again and he's now zooming around the tank .

 

What was the salinity in the tank that shark came from? I can see salinity being an issue if the shark came from freshwater but the op stated it came from a saltwater tank.

 

Leave the heater unplugged to see if he calms down.

 

yes, try unplugging the heater and leaving it unplugged although it would seem that it wouldn't go toward the heater if it was voltage?? what is the temperature of the tank?

 

Electroreception

sharks and rays are attracted to electrical current. That is how they sense their food basically.
