I lost one of those half banded eels I bought on saturday the most active one as well saw him last night on the substrate but seemed ok this morning saw him on his back bearly alive noticed a red streak near the anal area have had this before with newly bought algae eaters where 2 out of 6 deied within days of buying them . At first I could'nt find the other one as he had buried himself in the sand managed to catch him and check him he seems ok. Funny how the one that died was always on top of the substrate and never buried himself in the sand substrate was wondering wether he was too week in the first place
