Here are some new pictures of the sharks and their tankmates, I think these are the first one's since I got a dslr. They should look better than the phone pictures.
Yeah. I use a 1/3 or 1/4 HP jbj chiller (I forget which it is) to keep them at 62°. The chiller turns on maybe once every two hours for about 5 mins. My basement stays about 65° year-round; my electricity costs have been minimal with it.nice chain cat sharks running a chiller?
During the day they are not very active. At night they spend most of the night swimming. If they notice me in the room the become very active regardless of what time of day it is.Good looking sharks! How active are these little guys?
