I always try to find the most pathetic and sickly bettas that no one else will choose---I wasn't set up for more than 3 bettas today, but I saw a 4th one that was doing poorly and dull-colored (I was tempted to pour him out of his tiny container and into one of the "real" fish tanks so maybe he'd recover & someone would buy him, but there were too many workers milling around. Dangit!). I haven't gotten to name any of them yet....So here's one of the males---I put him in a 3-gallon 360 AquaView but without the bubbler and the LED lights:
Not sure if those are blood streaks or coloring on his tail, so I put a Fungus Clear fizz tablet in the water (Nitrofurazone).
The other 2 are small/young, a male and female I have in a 10-gallon w/a divider (thank you DIY article!!!). The male's fins are a little ragged, so added a fizz tablet to the water, and the female looks like she has gill mites or flukes as well as fish lice, so I added a Parasite Clear fizz tab also (Metronidazole, praziquantel, diflubenzuron, acriflavine). In the first picture, the female actually does have a white dot on her butt that you can see here:
Another one of the female--here you can kind of see her gills w/parasites:
Female staring at her roommate!
A couple of the male---hopefully the nitrofurazone will clear up his ragged fins and what appears to be blood spots (but could be coloring?).
Does anyone else out there run a "rescue hospital" for these guys like I seem to be doing?
I always check that area by the sink at WalMart---that's where they put the youngest and sickliest fish. I have a love/hate relationship with WalMart.
