I have no idea how they are I cant find any in the tank. I have since had another spawing and these were all dark colored. and now I cant seem to see any in the tank again. I dont know if they are hiding well or dead. I am hoping they are hiding. This tank has alot of struckture and is heavily planted so they very well could be hiding . They seem to be very easy to breed. I have several caves and tubes and a couple burritos in the tank and just drop the water temp b y a couple degrees when I do water changes and vala a spawn in a few days.
