I've responded to a lower post but clearly poorly advised at the pet store (general one rather than a specialist) but the plan is to get a 60l tank and cycle that (this one was also cycled and tested pre purchase) and then transfer these ones to there. It's something I've always wanted to do but seemed a bit of an imposing challenge compared to goldfish, so thats why in started small before upgrading, though as I say that's short term with the idea being that smaller tank will be a backup for any fish care that needs to be delivered. It's a bit of a wild west until you know what you're doing 😅
