Most real established keepers don't dig man made mutations .
Discus like rams are really well/ properly kept by those of us who are carried away to some extreme and looking for 'perfection' .
Best said by one old school keeper on the topic of long fin angels or discus " If I wanted a long fin mutation I would just keep goldfish". I do think there are beautiful goldfish ,but understand his comment .
I understand that and actually have found very little interest among keepers for long fin rams ..
I personally see no appeal at all for long fin /bulldog discus ? The rams I am undecided on ..I like the definition a standard fin gives and I will agree most long fins look ' not right ' , but a well bred / raised long fin ram is a quality sight to see IMO .
