this is Falkor my senegal bichir and i just purchased him last week he has been active in the tank and mainly stayed on the bottom unless he needs his air & last night he was still acting completely normal and this morning when i went to feed the fish he was up in the corner and i noticed he hasn’t moved still all day and he’s beginning to worry me he has these red lines on his fins and he won’t swim actively around the tank he just waits until he sinks down and swims back up & it seems that the african cichlid has been protecting him all morning as well because she hasn’t left his side please help!!
