well i washed my bucket out that i use for filling his tank. Several times to make sure no hair from me or my furry animals was in it. I checked the sides and everything. I poured in the water,and what do you know weird stringy hair thingys in the water. So now im thinking whatever it is,is coming from the tap water. Cause it doesnt look my hair or my animals hair. Now couple times bunny or kitty hair did drop in the tank but i picked it right out and you could tell that it was that. This is kinda well not white,but not black,cant really describe what it looks like. Colorwise. but its stringy and looks like really thin piece of hair. Now i came to this conclusion because i just refilled my cats water fountain thing and saw the same thing in their after i cleaned it and poured new water in. Im really wondering what it is. The filter on the cat fountain doesnt seem to catch it either too small i guess. Im perplexed. Really hope its nothing bad and will hurt fishy. I just dunno now. He keeps opening his mouth every lil while (more than normal) so i think the hair thing is bothering him a bit. I just cant get it out though. Cant exactly grab him and pull it out. Or can i lol. Im afraid of hurting him. Hes not like my other animals that you can hold. So i dunno.
