just wondering if I should be worried about these little guys. About the size of a grain of salt and found them all over a clay pot I recently put into tank. Also just added a salvini to tank. They are so small its hard to get great pics. They r kinda freaking me out when I look in the tank. Water seems good to me 0 ammonia 0 nitrites 20 nitrates temp 78-80 ph right around 7. 20 gallon and have a BP and salvini in there right now trying to get them to breed.
