Thanks for the help. I will be upgrading my tank to a 125 shortly and will get another shark for it. And I keep the cat out of the fish room, just wanted to get a nice pic the other day :)
I have a bit of a dumb question but was just wondering how columbian sharks normally behave. Mine is about 3" long and does nothing but lay at the bottom. I bought it about a month ago and am a bit worried about it. My water conditions are fine and its been eating, but its kind of pale. Whenever...
If your having a lot of algae growth it may be caused be the tpye of lighting you have/ leaving lights on too long. You may also want to check your nitrates.
Just a thought :)
