I have a few questions regarding my kuhli loaches. The other day I noticed a tiny brownish worm-like creature (5mm in length maybe?) serpenting through the water. Its movement resembled that of my 2 kuhli loaches. I dont have pictures because as I was examining it, it was gobbled up by one of my fish. Was it an infant kuhli or some other organism that got in there somehow? Second, if my loaches haven't bred yet, how would I create ideal conditions to get them to?
