Thank you for responding, and sorry to hear about Flame. I'd been keeping up with your posts about him.
I have uploaded a picture of Lowie (it's my first time, so I hope it worked. I attached it).
Some info I did not mention in my last post is: Lowie is housed with 1 zebra danio. He has been in this new 10 gallon tank for 3 weeks now. He was previously in a vase, and seemed pretty happy (was making his bubble nests) After some research I decided to give him more space. (He did not appreciate water changes in his vase) they seemed to stress him out. I also decided to get him some tank buddies. Reacted with curiosity, no hostility at all. But now he has these little fuzzy growths. The danio does not have them. Could it be the cycling of the tank that is stressing him out? I have yet to take it in to my local pet shop to be tested.
I have conditioned and changed the water (15%). I also put 2 tablespoons of aquarium salt, and turned his lighs off at night. My next thought is to purchase a heater... any suggestions?

Thanks a bunch!
