When to collect fry?

[Errbill]

Shouldn’t make a massive difference either way, unless you have rocks or wood that count alter the ph slightly

I used a few slate pieces that were in the main tank but nothing that alters the Ph.
How often should I do a water change and how much should I change at a time do you reckon?

Same as for any tank, weekly or more is best. The more you change, the quicker they’ll grow.

Thanks,I’ll do it every other day.
I do the main tank once a week bout 25%.
I’ve bought some instant brine shrimp and will be feeding them 3 times a day.
Just tried the first batch but they didn’t seem too bothered- will keep trying
