Well hello there, a week ago I bought 3 baby yo-yo loaches. They all seemed healthy except for one, in particular. This yo-yo loach is a bit fat and I have no idea why. I don't think it's pregnant because as I said they are quite young. (By the way, it came from the shop like this). I'll attach some pictures but they are not that good as he's a fast fella and also hides a lot.
