Well, I suggest putting up some pics. Please answer all questions in the sticky thread.
Good move removing the gravel, etc.
I suggest you don't add salt to the water if you see pine coning.
The only problem with euthanasia is that you never really know if there might be some chances of recovery.
Also, It may not always be dropsy. Remember that dropsy is more like a symptom (or a group of symptoms- syndrome) which is indicative of a much more serious illness like kidney failure, severe bacterial infection, etc.
I suggest that you please post pics & fill out the answers to the questions in the sticky thread asap.
Here's some info on dropsy:
bloated belly and raised scale = dropsy
close up of raised scales
This is a most common and most fatal
betta disease. oftentimes linked to the feeding of live foods
, especially black worms. Very little is know about it, but what causes the raised scales is fluid building up under the skin, inside the betta's tissue. Usually what causes fluid to build up is simple kidney failure
. And as you know, once the kidneys fail, the body dies. I think that is why we have had so little luck (mmmmm... Let me rephrase, NO LUCK AT ALL) in treating successfully bettas with dropsy. Although dropsy (the symptom) itself is not contagious, BACTERIA THAT CAUSE THE KIDNEY FAILURE in the first place usually are very very contagious
. Since I stopped feeding live worms to my bettas I have not seen one single case of dropsy in my fishroom :). Thank God!
It is easy to diagnose a betta with Dropsy: Look for two signs: an abnormally big (bloated) belly
and if you look at betta from the top, raised scales
. Scales will look like an open pine cone
. If you see this, you are out of luck, and so is Betta. He will soon go to betta heaven :((…
No known cure
. Keep water clean, keep him AWAY from any other bettas etc… On occasion, in the case of a very mild raised scales, I have seen bettas recover on their own. But I suspect that this is because those cases are NOT real dropsy. Real dropsy always kills. So I guess you have to wait and see what happens. Treating is pretty useless. It may take up to 15 days for betta to die, though usually about 5 days. Any betta with dropsy should be immediately ISOLATED!!!!
Prayer may not hurt.
