Just a suggestion.... if your new guy starts eating the fry you can use a big plastic tote to hold them while you get the 55 fixed or replaced. I have had to do that a few times with fish in an emergency when I have no suitable tanks at the moment. Hob filters fit right on the side and I’m sure canisters would work fine too.
I’m sure you probably already know this, but I figured it never hurts to put it out there
The fry are looking great! You have a ton of them!
My favorite is the little guy from the first batch. So adorable!
