'Fancy' goldfish are essentially inbred carp.
Orandas are a fucking hideous mutation.
Mutated lionheads with thier fleshy alien head growth are inbred with mutated fantails and their deformed spine and grotesque split caudal fin.
In the wild, these mutations wouldn't last about 5 minutes.
The deformed spine and mutated fins make it difficult for these mutant fish to swim. The deformed air sac makes it near impossible for 'fancy' goldfish to maintain proper orientation in the water.
Breeders cull thousands of mutant goldfish to develop a 'pure' strain of these varieties that are pleasing to certain people.
Pretty sick how some people can find deformities appealing.
Anyway, being a carp, goldfish are very dirty and very hardy.
Don't overfeed these gluttons or they will overeat and quickly foul the water. Doesn't matter if the water is aerated, these things ahve a very short life expectancy anyway.
Up until the past few years I kept several tanks of African Cichlids. At one point I made decent money breeding them and selling fry to other breeders and pet stores.
I kept mostly julidochomis..
Pretty interesting fish... aggressive, territorial and carnivorous.
