I think I am glad I dont have to catch your paros in there, – that is a real problem. So best thing probably to not.
Or if you need to, you will have to have a lot of patience. I am sure that when, as I, you have caught a lot of paros, it actually is possible, even they fly around, – to get them trapped somehow at the frontglas and put a net over them, – but in such a big tank, I think it must be really difficult.
If those new ones you got, are wildcaught, that also means that they must have gone through a lot of changes and travel lately, which would make them more delicate.
I often find with paros that I buy wildcaught, – are ‘delicate’, but I alway put that down to stress from the journey and changes in conditions. I often think that I have quite many losses with those fish. But those that settle seem as tough as the ones that have been breed.
