A few months back I bought (2) Bristlenose Plecos to clear up some diatom blooms and housed them in separate tanks. About 10 days ago I put them in the same tank and then tonight while doing a water change I saw something orange in the conch shell with one of the plecos. I lifted the Shell up and saw this little guy. They are currently in a tank with Brevis Shell Dwellers so I do not expect these fry to make it long but it was still cool to see them spawn in a shell. I have no clue how many are actually in there but here is a photo of one of them.
