I found my Senagalus like this yesterday with a red mark on his underside & was a little slugish . I did a 20% WC & cleaned out my ehiem external (left the internal alone) & removed some wood from the tank
This is him today as you can see he look's much worse . Has anyone had this problem ? Any advice please i'm pretty worried now .

He is in a 5 foot community sand tank , no big boy's in there the biggest thing's are Synodontis & Suncat's . I have ran out of test strip's so can tell you the perameter's . I am feeding him catfish pellet's ,earthworm's & prawn's the only change is bloodworm pellet's that i recently bought
