Addy has a completely nonfunctional swim bladder. Without this harness she sinks on her side on the bottom of the tank. In it, she can swim around in the tank (although she can't go higher or lower in the water), and live a relatively normal life.
This harness came about by lots of trial and error, but started with a basic idea from this site: http://www.geocities.com/swimbladderhelp/welcome.html
There are some images of previous prototypes are here: http://www.sullivanet.com/misc/fishie/fishpics.htm
At the start of this odyssey she went through two rounds of Baytril injections, but her swim bladder was too far gone for the antibiotics to help.
Here's Addy in her harness...
The cut out pieces on the side are optional. I don't always do that, so they don't appear on the diagrams below.
Here's the layout of the harness...
And here's how it goes on...
And the results...
The harness isn't ideal, obviously. The harness sometimes rubs a sore or tender spot, and it does restrict her movement vertically in the tank. But it has given her at least six months and counting beyond what she would have had without it. Because she can't bottomfeed or otherwise find food on her own, I have to hand-feed her twice a day. She's gotten used to taking pellets from my fingers, and gets all excited, wiggling to get closer, when she sees The Hand coming toward her.
SUPPLIES:
The flannel is just plain, white, 100% cotton flannel--of the type sold for diapers, I think! I get mine in the fabric store or craft department of a department store. To reduce fraying I cut it with a pinking shears.
After about five days in the water the flannel in the harness gets slimy and starts to fray and fall apart, so the harness needs to be replaced at least once a week.
The bobbers are from the fishing supply department.
The lead sinkers are, too. I use the reusable type that have to be opened and closed with a flat-nosed pliers. They're frustrating to work with, but they do the trick. You can reuse them a few times before they get too hard to open and close and have to replaced.
Any thread would probably work to attach the bobbers, but I use carpet or upholstery thread because it's stronger.
The twist ties are the kind that come with bread wrappers or fresh produce bags. They last a month or so before they start to fall apart.
I hope this helps some other fish out there!
If you have any more questions just ask me.
