Hey all I have a question. I have 2 senegals (the petsmart kind) and have had them for about 3 week's. They are approx 4 to 5 inches long. Well I looked in the tank today and noticed these little thing's swimming around in there. Im thinking the best way to discribe them is to say they are very very thin and very wiggly like a very skinny little worm. Anyone know what the heck this is? I would find it hard to believe that these thing's had babies. Please help because I dont want my fish to get parasites if that is what this is. thank you all.
