I am thinking two females. They get those short bristles on the front like that but rarely up the face the way usually males do. However, I can also see body shape differences that would suggest both sexes are present. You need to have caves for plecos. Males will claim them and that is a good clue to sexing. Females may use them but they normally do not claim them.
Plecos want a tight fit in caves ib terms of height and width, Depth should be a a bit more than the length of the biggest fish. If the plecos get bigger over time you may need to get bigger caves.
Brilliant, thank you! I've seen at least one of them pop into a pleco cave, but didn't claim it, but they're also still young, and might prefer different caves too. They do have a different size and shape for sure, even though they were the same age, used to be about the same size, and have been raised in the same conditions/tank/foods etc. Fingers crossed
I do have two pleco caves that should be a tight, but not too tight fit! I've wanted to get more, different shapes, but hard to find online, will take a trip to the fish store soon!
As an extra - since I'm closing down a tank and have been moving fish, I just moved another three young bronze cories meant for rehoming to a different tank, where they've joining three other young bronzes due for rehoming. They've been in the tank for maybe an hour, and I'm seeing a lot of chasing and pre-spawning behaviour... aarrggh! I'm over-run with bronze cory fry already...
