Gouda morning everyone! so i bought 2 rope/reed fish (Erpetoichthys calabaricus) a couple of months ago. one is about 4 inch and the other is about 3. I have a 60 gallon with some tetras, gudgeon gobys, dwarf neons, sword tail, rainbow shark, and catfish. I keep up on water changes every week and tank cleaning every month. all my fish are active and get along very well. I feed them frozen blood worms and sinking wafers for the bottom feeders. I first noticed this 'issue' about a month ago, but they were so small and oddly places that i thought nothing of it and passed it as maybe part of the gills were protruding, as i always watch them eat during feeding and this is when i noticed it. BOTH of my rope fish have began growing literal axolotl tentacles behind their heads, above the fins and gills. I can only describe them as little pink looking feathers on either side of the head. they both have them but the 4'' you can see more clearly. They act no different and appears to have absolutely no effect on them yet, still very healthy and active, eating at every feeding. i called the store where i bought them and they have never heard of anything like that and said i maybe got a different species of rope fish. There is nothing about it on the internet that i can find. any advice would be very very appreciated.
