Regular Member usmgp1 Posted January 13, 2013 Regular Member Share Posted January 13, 2013 Is it safe to put an older fry in with the younger ones or will the older ones eat or hurt the younger fry? 0 Quote Link to comment Share on other sites More sharing options...
Regular Member number20121 Posted January 13, 2013 Regular Member Share Posted January 13, 2013 It is not uncommon that older, larger ones may eat smaller ones. I personally don't know what age/size difference this is, but when in doubt, keep them separated 0 Quote Link to comment Share on other sites More sharing options...
Regular Member shakaho Posted January 13, 2013 Regular Member Share Posted January 13, 2013 Definitely not, if you want to keep the little ones. 0 Quote Link to comment Share on other sites More sharing options...
Regular Member mikroll Posted January 13, 2013 Regular Member Share Posted January 13, 2013 .... the older ones eat or hurt the younger fry? yes , just like Hannible the canibile. a good size big sister can eat 15 to 60 little brother a day. and little brother is excellent live fresh food too! Ugh. 0 Quote Link to comment Share on other sites More sharing options...

Ugh. Just out of personal curiosity: Even at only 9 days age difference? I mean, I am keeping my two (lol) fry separate too, and they are about 2 weeks age difference. But I know that I am paranoid and overly cautious, so I didn't think that I'd make a good example oO Excuse me guys for all the notification about being quoted.

At least with a lot of fry as some will grow much faster and be bigger and stronger than the rest and then become predators. with only two perhaps your OK. just see that they get enough live food such as artemia or mosquito larva. 0 Quote Link to comment Share on other sites More sharing options...
Regular Member GoldenSpoiledRotten Posted January 14, 2013 Regular Member Share Posted January 14, 2013 I recently saw someone on here whose larger fry from the same spawn ate a smaller one. 0 Quote Link to comment Share on other sites More sharing options...
Regular Member bodoba Posted January 14, 2013 Regular Member Share Posted January 14, 2013 From a pond standpoint you can conceivably have more than one spawning of fry growing at the same times. Providing lots of shelter with floating plants like duckweed keep them at the surface and at the food source. Normally in ponds your spawns are in the 1000s so there is calculable loss from parental and sibling predation. Moving on to smaller spawns from tank eggs. Providing the same conditions of lots of shelter and lots of food should cut down on the predation. Also since you check on your fry more than once a day you can remove the fry that are growing faster that pose a threat and give them their own space. It's up to you to determine whether you want to do this. The benefits are less containers to deal with. Downfalls are more than just predation. Increasing your population in a tank may cause you to increase your water changes. You'll have to have more food ready at a time. Are you prepared for these changes that may occur? From a growth standpoint, everything should even out between day 30-50 of life and you can safely combine them then 0 Quote Link to comment Share on other sites More sharing options...
Regular Member nick11380 Posted January 14, 2013 Regular Member Share Posted January 14, 2013 It's safe to put older fry with younger fry as long as the younger fry are too big to eat. 0 Quote Link to comment Share on other sites More sharing options...
