Hi all.
I've been having a few dead goldies issues. Like one or two a day, getting progressively worse.
There is no problems with them physically, no cotton wool, the gills look healthy, no scales missing, just like the live fish, only dead. I cut one open, but buggered if I know what I was looking at, looked like fish guts to me. And none really seem to be acting abnormally, but I've got 100 of them in there, and it's tricky to spot one or two acting weirdly
I've salted to 2ppt as a precaution, but I have a feeling that's not it.
Some of them are new fish, but I've been religious with treating them with some of the medication in their bags before they go in (they aren't for eating, so I see no problem with this, just to knock any parasite, or fungus on the head).
The only change is in the diet. I've got 6mm floating pellets for another fish, I hadn't used it because it was too big, and I had the sinking types to use up first. I'd been crushing them up first (but some of the larger get through), and mixing them with the sinking type to try and get them used to it, and now that I'm introducing more of the floating, and less of the sinking, I end up with more dying.
I stopped feeding them on saturday, and since then I've had no dead fish (granted too small of a time to tell).
I did some googling on goldfish, and it says to avoid the floating type because it can mess with the insestinal track which follows on to the boyancy of the fish, and cause issues (I'm guessing death).
I've just ordered some more feed, sinking 2mm, silver perch type pellets, and will arrive hopefully tomorrow or wednesday, so they'll be on a diet until then, will see if I get any more floaters.
Let me know if I'm right off the track here, but I thought this might be a help to somebody else, and I'll report back in if others die. And another learning experience for me
