    Strange one, any ideas??

    So got a bit of an odd situation going on in pond, my sturgeon is acting strange, even more so than usual just constantly bobbing up and down/tailwalking around pond

    Also, I ended up with lots of small roach/rudd in my pond a couple of years ago by mistake (don’t ask)
    and over the last couple of days they have started dying off one by one, fished one out couple of days back and another 2 today

    Putting 2 and 2 together, I know on some medications it states not suitable for “other” pond fish ie Rudd/orfe & sturgeon so what exactly does affect these other fish and not koi?

    Koi seem ok ish for now, slowed down with temp drops but seem ok looking for food etc

    Air stones filtration etc still working no changes there, and haven’t used any treatments in pond, struggling to think what the issue could be

    Can’t put a video on for some reason but it’s just constantly doing this around pond and swimming on its back

    How old is your sturgeon. I had one that was about 18 years old, a big bugger at 4ft 10inch, and started acting similar to yours, tail walking and jumping. I rang a vet that specialises in fish and he said sturgeon are prone to brain tumours in their later years. Unfortunately I lost mine as he jumped out of the pond and I didn’t find him in time.

    Not too sure tbh we’ve had it about 2 maybe 3 years but it came from a family members pond who had had it a while but unsure of just how long

    After a pH crash, the fish will be suffering from acidosis and be very stressed so it's important to raise the pH correctly rather than just add sodium bicarbonate without regard to how quickly the pH is raised or you may cause even more stress and raise the level of toxic free ammonia to a harmful value. This is how to recover from the crash correctly:

    It was indeed a ph crash, I tested this morning and it was 5 ish!

    Tested the tap water which was 7.0-7.5

    I’ve changed a bit of water through the nexus and added what bicarb I had to hand, I’ll restock with more today and test/repeat tomorrow

    Just one more roach dead this morning other stuff sulking but still alive including sturgeon
