i wasnt paying close attention to the ERHs in my tank. there are 4 of them, but recently, i noticed that one ERH's anal fin was slightly different from the other 3. it was shorter, and was broader as compared to the rest of them.
i am wondering if they are of the same, or are 2 different species altogether. i've had them since they were 1.5'' to their current 6''. just curious. i hope someone here can help
i've attached pictures of my red hooks. look at the anal fins for comparison.
