Hello. I’ve got a 350-ish gallon outdoor pond with 10 or so assorted Comets & a couple Koi. Generally everyone came through winter ok, with the exception of this guy.
We’ve had this pond for close to 20 years and have had fish age out & expire, which is what I thought was happening with this poor guy. However, he/she has been lying nearly motionless for several weeks now, only moving slightly from time to time. If touched or disturbed it will swim around a bit, only to quickly come to rest again. It can remain in the same spot for days.
Any thoughts on what could be going on?
Thanks in advance
