I read this thread and came back to it three times now
after reading the suggestions made and OP wanting quickly maturing plecos makes it difficult. One reason plecos are so expensive is bc they take time to mature and breed, they are not a quick cash kind of deal.
sure bn will breed quickly but before you know it you’ve flooded the local market and now have no where to off load all your babies. Your bn don’t know the market is flooded and they will continue to breed haha
I liked the OP’s comment of wanting to find something they are interested in keeping as this will ensure they stay focused on the group of plecos.
green phantoms are bred in aquariums now but I’m not sure how easily they are bred…I assume not too easily as you don’t often hear of it.
most hypansistrous and ansistrous plecos will easily bred for you, just takes time to raise them.
the world of ansistrous plecos is far and wide if you enjoy the Bn maybe one of these types will spark your interest
