I have had a female betta for almost 3 years now, I bought her from one of those little jars from walmart, I felt sooo bad. She was placed in little betta tank when I first got her...then a few months later a large bowl and now she is a 5 gallon tank by herself. She grew a lot since I've had her, she is as big as my oldest male betta in body size.
I know she is quite old now, she has slight cataracts on her eyes....but I noticed she has gotten quite fat! She always did when she was ready to breed (I never have bred her though) but now it is unusal, I am afraid it could be dropsy. My tank is very clean and has a great filter, so I was wondering how she could get such a disease, but as you all know that's nature right.
Anyways Her whole body swollen looking, but with no pine coning of the scales. She has beautiful colors still, and she is still a very aggressive eater. She swims quite a bit, she was always active, she is a little less active now, but I wouldn't say that part is a concern yet. But sometimes it appears that she has trouble keeping upright when she swims close to the filter now (weakness swimming?)
I was wondering if I should be concerned that she may have dropsy (is this common in older fish?) I would like to try to treat her as she has been through a lot with me, but is there a point if it is dropsy? has anyone had success with treating it?
