L-239 Blue Panaque Pleco
The L-239 pleco is a solid navy blue, very unique for saltwater or freshwater fish. Blue panaques are scavengers but also require veggies, so it is a good idea to add algae veggie wafers a few times a week to the aquarium. The blue panaque is peaceful and only grows to six inches, but it will not tolerate temperatures below 75 degrees. These beautiful exotic aquarium fish tend to break out with ich when stressed, and if that occurs, treat with malachite green. The L-239 pleco is wild-caught in Colombia and varies in size when exported, from 2 inches to 4 inches. And of course these guys like a piece of driftwood.

The blue color is striking and adds a unique touch to my tank. I feed it algae wafers twice a week and it’s very active. It’s peaceful and doesn’t bother other fish. I keep it in a 20-gallon tank with driftwood, and it seems happy.

Arrived quickly and the fish looks healthy. I noticed it’s a bit shy at first but has settled in well. I’ve been feeding it veggie wafers weekly and it’s eating well. The size is smaller than expected, around 3 inches now.
