The fins are larger on the sailfin...but almost all the "common plecos" (Hypostomus plecostomus) on the market are actually sailfin plecos (Glyptoperichthys gibbiceps).
I was wondering would a Ancistrus plec a blackmoor and a common goldfish go well together in my small cold water tank?
Ancistrus Plecos (Bristlenose catfish) are tropical fish and do
not like to go below 70F. They prefer to be kept around 75F to 80F.
The other 2 goldfish are OK together but the catfish would die in
the cold water eventually
