I have a 35 gal with 2 moores (about 7 inches and, as far as I could tell, both male) and 2 dojo loaches (about 2 1/2 inches). Cleaned off algae and changed some water today, noticed what appears to be slightly greenish (but clear) eggs on the tank wall near the bottom. They are in a cluster of about 20 and each "egg" is approximately 1 mm in diameter. No other fish in the tank though I added two bunches of anacharis about a month ago. Any ideas?
