Yue is kept in a one-gallon critter keeper. He has a 10W heater that keeps his tank about 72-75 degrees (I have glass thermometer). Right now it's about 72. My house can be kinda cold in the winter (though summertime is the complete opposite). No filter or aeration. No tank mates. He's kept with one silk plant and some gravel.
I feed all of my boys Aqueon betta pellets, usually 3-4 pellets twice a day, though I will have them fast or cut down on amount/times per day the rare occasion that they seem a bit bloated.
I try to do a 100% change once a week, though I haven't been as good as I should have been the last few weeks (and I'm sure this is why he has fin rot. *sigh*). I add Stress Coat to the water when I change it, and sometimes aquarium salt just in case.
I do not have a test kit. I'm going to get one as soon as I'm paid (which should be sometime this week) so recommendations would be great.
Symptoms and Treatment
His tail is ragged and missing pieces, as are his bottom fins (the two long front ones and the larger one). He also has a kinked spine (which he's had since I got him, though it got worse as he became an adult). He also has a two red spots on his head and right above his mouth that didn't go away with Fungus Eleminator and have remained the same size and shape since they appeared about four weeks ago.
His behavior is the same as usual. Active, curious, and exuberant about food.
I did a 100% water change and added aquarium salt. I removed the gravel but kept the plant. A few hours later I went by Petsmart and picked up Tetracycline and added the first dose of that (Is it safe with aquarium salt? This just occurred to me now...).
Honestly, it's been one thing after another with this guy and I've never had sick fish before, so sometimes I'm worried he might have Tuberculosis or something. I got him about three and a half months ago when he was still little, so I'm guessing he's about 6 months. I believe he's had columnaris (it was hard to tell though, since he's white, but I thought I saw whiter spots near his mouth and gills, so erred on the side of caution). I treated him with Fungus eliminator and as said previously the red spots didn't go away, but he seemed to perk up and his blue colors from when he was younger came back. I'm starting to also wonder if he's got an internal parasite, since he's always been skinny. Then there's the spine, and now the fin rot.
I'm hoping he's just a little weaker than my other boys and I just have to be more careful and do frequent testings and water changes for him, because I can and am willing to do that. But I have no idea how long it takes tuberculosis to show up and then kill the fish, and he has a lot of the symptoms listed.. (I've been using gloves to clean his tank for the past month and I take care to keep anything to do with him separate from my other three).
Basically, I guess what I want to know is, am I doing the right treatment? Does he have tuberculosis? Do I need a better heater, and if so where can I find one that will fit a one-gallon? What test kits do you recommend for ammonia especially? (Also, should I treat him for internal parasites once he's healed from the fin rot?)
Before Columnaris Treatment: (red forehead spot)
Two months-ish ago: (no forehead spot)
