Tank after net

[Brengun]

I have my 7 zebs in a broodnet until they get eating well and grow a bit.
The tank is 50cm and contains 5 juvi bronze corydoras, and 10 sparkling gourami.
The substrate is gravel and sand, there are several plants and a couple of little caves ready for the zebs.

I am just thinking ahead here, but should I think about moving out all the corydoras, and would the sparkling gourami be ok to stay?

Also, should I gradually siphon out the substrate over time with wc so the zebs have a nice smooth bottom?

At the same time, I could gradually pot different plants so they can be moved around the tank. What do you think?

Hi
Remove the gourami and the corys although corys are less of a threat to the zebs they will eat there food. You should be ok sucking the gravel sand out over time I did that myself in one tank last year the bare bottom tanks don't look as good but are far easier to keep clean
