Hello, I own 1 male (red) and 1 female betta (bluish green). I have had them for a month now. When I got them the female had thorn fins and the male was in good shape so he was aggressive towards her and he built a bubble nest as soon as I put them in the bowl, so I guessed that he wanted to mate but she wasn't ready. I separated them so she could recover by putting her in a jar (filled to the top) and leaving him in the bowl.
She fully recovered within a week and her fins grew back completely.
She's been fine ever since and she even has the white spot under the pelvic fin, which means that she is ready to mate.
He, however suffered a disease which I recognized as a simple cold.
His bowl wasn't covered at the time and I've been opening windows so it must have been that the cold draft of air made him ill. I stopped exposing them to any temperature change and always made sure that their water is warm enough. I bought him glass rocks and a plastic plant to make him feel better after I found out that they hate an empty tank. I also bought Dajana Aloe Gel for wound healing and have been mixing a few drops of it when I do the water change. Also, I wanted to buy aquarium salt but the pet shop didn't have any and the guy who works there told me that I can use kitchen salt so I've been putting a pinch of salt when I do the water change. He started getting better from the first treatment. (I did 50% water change every day for the first 4 days of treatment and cleaned the leftover food to keep the tank clean) 10 days later (now) his fins have completely recovered and he is very active and happy (he used to stay in one place all day and barely eat).
I am so happy now and I want to know... Should I should keep treating him with aloe gel and salt and for how long?
I also feed him live tiny spiders and mosquitoes which I catch around the house (1 per day along with regular food) and he seems to enjoy them. Also, he stopped eating 'the red food' even now when he is doing well. Why did he stop eating 'the red food'? He eats all the meal-worms I give him.
He didn't build a bubble nest since he got ill and I keep the female's jar so close to his bowl that it is touching it so they could see eachother. Why isn't he building bubble nests? Does he need more time to fully recover to do this?
Other than this, they are well. The picture below is him (down: when he was well, and up: when he got ill).
He looks great now.
I have a 1 gallon fish bowl with no thermometer nor a filter. The bowl is not heated. I started covering it a while ago. Green glass "rocks" at the bottom and one green plastic plant in the bowl. The picture below was taken as soon as I got them, I just wanted to show you that they do have enough space, since I see a lot of hateful comments concerning the tank size.
I feed them dried meal-worms (a pinch a day) and red cubes of some sort. The picture below was taken by me.
The lady at the fish store told me to give them just a couple every day.
I change the water every 4 days and I usually do an 80% water change. I use stale tap water (I fill a large pot with tap water and use it after 2-3 days). I have never checked any water values because my bettas were always fine with it.
I have treated him well, and this may be a good advice for someone who was the same problem with their betta but I need advice myself.
I tried to provide all the details you need to answer my questions. Thanks for reading!
