I'm new here hope i'm posting in the correct place.
I currently have 2 tropical fish tanks, On cleaning out the 1st i have found several not just a few ( talking over 30 baby plecos they are very tiny ) I have added a couple of pictures of a couple but not too clear as I used my phone. There are mixed in colour , some are the average dark and others are yellow/whitey as seen in the picture.
I'm not a breeder so more luck than judgement, ( I've never bred anything before lol!)
I have separated the bigger fish into my 4 ft aquarium and left all the babies in a smaller tank so there isn't anything else in there that could eat them.
The babies currently swimming across sides and bottom of my 1st tank, To the point where my gravel looks like it is moving.
As i'm not a breeder just looking for any further advise to care for these?
