I have an unusual question about my goldfish, hope someone can answer it
Okay so I have three goldfish in a 40 gallon setup. They're quite happy, I'm just worried about my lionhead, Kiwi. It's three years old now, and compared to his tankmates still quite small. Someone in a fish store mentioned to me that goldfish can get stunted. I have two orandas in the tank with him, Chicko who has grown to almost 5 inches(also 3 years old), Pinky a redcap who is about 3 inches (2 years old). Kiwi, who is three years old is the same size as Pinky, about 3 inches. The thing with Kiwi though, is after I bought him I realized that its tail fin is slightly deformed (one half is bent over) which causes him to swim upside down because he loses his balance all the time. I'm wondering if because of his disability his growth may have been stunted? Also I'm worried that as the other two grow bigger, it'll be more difficult for Kiwi to get any share of the food. Any ideas?

Thanks! I'll wait patiently I guess I just need some good advice :)

I'm not a goldfish expert but I think that the reason Kiwi is swimming upside down is not because of the tail. We need pics to verify this, but from your description, it seems that the tail deformity isn't that severe. I've seen goldfish with very damaged tails but this doesn't cause them to swim upside down. They mostly aren't able to move or just stay at the bottom.

I think your goldfish has swim bladder problems, that's why it goes upside down. There are many prossible causes for swim bladder problems, and I guess it's Lupin's forte to explain that, not mine. hehe.

40 gallons seems OK for 3 goldfish. Could you post the exact dimensions (LxWxH) of the tank just to be sure?

Sure thing, uh I'm new to the forum so I'm not entirely sure how to add attachments of pictures...
Yeah I've heard about swim bladder problems, I just always assumed it was because of his tail that he would do that.
My tank size is 36 x 12 x 19
If you could let me know how to post the pics, I will do it :)

you can register at Image hosting, free photo sharing & video sharing at Photobucket (it's free) and upload your photos there. Just use the "insert image" button while replying here in the forums and paste the image URL in. Looking forward to the pics.

Hello and welcome to the forum. See if this helps any...

caroknap 11-22-2009 10:18 AM I don't know if the pictures are working, Sorry the background makes it difficult to see the tail but one of them you can see how the fold is very prominent and so his tail fin isn't balanced.
