a little over a week ago we bought all of our 11 fish at once from the same tank. first fish to ever go into the pond. ammonia 0 nitrite 0 gh and kh good
2000 gal pond with just the 11 4-5 in fish.
yesterday i didn't see "bones" all day and i was looking for him really well this morning during feeding and didn't see him either. so later in the morning i did see him kind of hanging at the surface. not tail up or down in good position but just still. he was moving fins and such but not swimming at all. when i would walk over he would swim off right away. he has been isolated from the other fish all day and i haven't seen him eat with the others either. a little while ago he was still at the surface just kind of riding the water.(hope you know what i mean) this time he didn't swim away he went to the bottom of the shallow part and i couldv'e picked him right up if i had wanted to.
now what could be the problem. is he just young and he has something wrong or could it be something else...what...
we intentionally got all the fish at once so we wouldn't have problems with parasites and such. what should i do. thanks for any advice.
