Reintroduce fish to pond? #1
Hi, am new to fish & ponds (bought house 1 month ago & inherited pond) and have an issue I hope you can help with.

We have 4 ordinary goldfish, 3 ornamental goldfish, 4 koi & 2 ghost koi. I've done all pond care (plants, cleaning, testing etc) & all fish are great. But a week ago one if the ordinary goldfish starting to swim upside down or with tail in air bobbing on surface. Then she would be floating on top under reeds & only moved when I would go out.

She has lump on one side & is bumped by other fish, pond shop guy said prob swim bladder disease, but lump could either be bloating or roe. He suggested moving to quarantine tank (after prep) and using Medifin, salts & green peas.

I did this yesterday & from second I moved to tank she seems perfect, swimming happy, no floating, no buoyancy issues.

My question is....do I reintroduce her to pond (after aclimitisation) or do I assume something in pond was stressing her or causing her an issue?

I have bought huge tank & am happy to keep her in aquarium, but don't want to keep her from other fish, have no clue on right decision.

Apologies if I'm acting a bit 'emotional' about a fish, but feel very responsible for them after last owner just left them 

Thanks, Cath x

Has the swelling gone down? I would not move the fish back yet, as it's possible it has an internal infection affecting the swimbladder. In cases like that, shallower water (as in the tank) can improve symptoms a lot, but moving back to the pond will cause it to start up again. Treat with a good anti-bacterial that deals with internal infections such as Esha 2000 or Waterlife Myxazin.

Swelling has reduced slightly, but still noticable.....she's doing great in the tank, but not eating. Have used tonic salt & Medifin, but will look at the treatments you have suggested also.

Thanks very much

Re: Reintroduce fish to pond? #4
Glad she's doing well in the tank - and, if there's any males-chasing-female behaviour going on, this will give her a break from that to improve, after which you can make a decision where she would best be kept long-term.

Are the peas out of their shells and chopped up? That might help (otherwise she might not recognise them as food), and garlic added to food can also be an appetite stimulant. Frozen/live bloodworm is another option - but not daily and should be part of a broader diet. Since I kept goldfish, I've noticed a few more nutritional products on the market specifically to address swimbladder malfunction problems - I'll see if I can find some links to them.

If, at any stage, you think her scales look raised, then stop the aquarium salt - this would indicate dropsy, in which case aquarium salt (sodium chloride) would worsen it but Epsom salt (magnesium sulphate) would be better in that case.

Absolutely no need to concern yourself about being 'emotional' over the fish - I'm *exactly* the same about my own/others' fish. I'm so glad that someone kind and caring and interested in the fishes' welfare has bought the house with a pond. :)

Thanks so much xx

Yes, peas out of shells & chopped but no interest yet, didn't know about garlic so thanks for that. Scales look good at min, but will keep an eye.

Thanks very much for the help x
