I have betta fry it has been 7 days since they hatched. There is about 50. They are swimming around and seem to be doing really well. The reason I ask how long they will live if not feed is – I only have frozen baby brine shrimp, the reason for this is the girl who works in the fish shop I go to said they would eat it no problems, she has always given me good advise, but when I was doing my research before breeding everyone said I should have live food like microworms or brine shrimp etc. The fish seem to be growing well, it is hard for me to see if there stomachs are full or not. I would like to know if they would be dead by now if they were not eating. I also did the boiled egg thing yesterday and gave them one feed of that.
