I do not know how this happened after 3 months of no problems, but this morning I fed my Neon Tertras their ground up flakes as I always have, with the filter off, but this time my Betta swam right through the cloud of food and it is stuck all over him! He does not like it one bit. He keeps swimming quickly I imagine to try and dislodge the debris from his scales but it is stuck on there real good. Will the food just dissolve after a day or so? I am so worried. He has been such a happy fish up until now. :(
