Help! Need to rehome Bristlenose catfish.

My son's bristlenose catfish have bred again and it is now too difficult for us as novices to care for them properly and we need to find a new home for them. We have moved the babies and the adult female (approx 4yo) plus 2 juvenile females (approx 1yo) into a small temporary tank (we also have a few female guppies in there) and need to rehome them to someone who know what they are doing! Happy for them to go with the complete tank as per pic including the heater and the hydra filter. Any advice or offers of a new home greatly appreciated. We are based in Suffolk. Thanks

How in the world did you catch all of those.

LOL I am having the same problem with BN Plecos. By total luck of the draw, I have a breeding pair in my 55-gallon community tank.
Yesterday I did my best to catch as many as I could for re-homing into another tank. I got tired of trying. Plants etc in the way, I would have to completely tear down the inside of my community tank in order to catch them. I could not even catch the grown breeding pair and gave up.
I caught a few of the babies but not even half before I gave up.

Uh oh! That's a whole lotta babies!! Congrats on somehow catching them all! And I really wish you luck on rehoming them!
Have you asked a local fish shop if they'd be willing to take them in? You might be able to sell them on Gumtree for £5 each possibly.
