Looking at all the pictures id say you have a very rough male. Hes trapped very hard. The first fish had a secondary fungal infection, ive had success with similar on l024 treating with acriflavin. I would try bathing the second fish in furan2 once a day for 3 days. Hope this helps

Following on from the breeding report i published. 20190127_130301.jpg Between days 12 and day 17 i lost around 20 fry. All started with the same symptoms which i have seen in other fry. Where the stomach/yolk begins to swell. The fish become a loner from the pack and occasionally dart irratically. ...

Or. If you are using r.o let the ph come down to around 5.9 over about a week. Then increase it instantly to around 7. They well be trapping within minutes.
