These Sterbais in my 20 gal are relentless. I fixed a clogged filter, did a 20% water change this morning and within minutes they were frantically circling each other. I think I id two females and 4 males so I lucked out with the ratio. They produced 50+ eggs this morning and I interfere by setting up a little breeder net cage and collected all the eggs I can see and placed them in it. They might continue but are eating breakfast now. I hatched another 50 or so of these guys’ fry previously spawned and they are growing out upstairs in my living room tank with the Adolfos. There are also around 20 or so young juveniles in the tank with the parents. I’m going to be overrun with sterbais but I love this species of cories.
