I am under the immpression they are spilo cf since they have what I think are serra specidic genes such as the dorsal fin pushed back, the pointy face and the mean demenior, I also thin that we purchased the fish from the same person
the odd thing is that i have 6 in a 20 gallon that are about 3 inches now and they all get along good...
i still think they are CF tho
but i havent ever had any other fish except pygo so hey take my advice with a grin of salt
also , mine might be bigger but mine have ALOT more red on their gill plates and chest
I think hollywood has enough natts on his hands. I thought he was a breeder.
Another thing to think about is that all the pics of spilocf I have seen do not have black terminal band on the tail. MIne dont, however he is much larger then yours. I would be very concerned that perhaps they are just natts.
S. spilopleura CF would be confused for S. rhombeus at this stage of the growth, if those fish were that species. These fish are robust in appearance. Therefore (until I receive a specimen to examine), my ID remains the same opinon without bias.
