I am running out of room to put tanks. I know you all say 1 gallon minimum, but if I take very good care of the jars and add plants and do daily water changes, would it be ok for the betta? The jars range from 1/4 to almost 1/2 gallon. I haven't worked out heating yet, but I am considering come of thse cheap aqueon ones that auto heat to 78. These may be temporary homes, or permanent for the bettas, basically I go to petco and buy bettas with minor problems (fungal infection, extreme fin rot, floating on top but breathing) and heal them, and 1/2 gallon jars would b good for that, right? I usually do 1 at a time in my 2.5, but it is in use. I have a TON of jars I found in the basement (ant used to live here..) should I go for it? Will the jars work?
I've heard moving sickly bettas to a large tank at first isn't a good idea, only because their muscles and bodies aren't used to swimming in large areas because they are kept in little cups. So maybe until they are healthy you could slowly increase the size of the tank...Maybe someone else can help you as well. Good luck.
I know a lot of breeders will keep bettas in jars like you are describing, but I think your main problem is going to be heating. One heater per jar doesn't sound like a good idea to me. Too many plugs, and I wouldn't want to take a risk with preset heaters and sick bettas. The way breeders heat that many jars is a space heater. I've heard of putting the jars in a large tank filled with water. Set the jars down in the water, heat the main tank water, and let the heat from the water transfer to the jars. You've got a few options, but I think it depends on just how many jars you want.
Try finding a long tank. My petsmart has a 15 long for 30.00.... 25 long for about 45 or so. no hood however. Second hand stores are your friends!
A 20 LONG can be divided 5 giving each betta 4 gallons.
Heating each individual jar will be costly, hard, and not worth the trouble. I've heard of heat pads being used, but they use a LOT of electricity... I heat a room for my bettas, which then the room itself is at about 80.
When I have "too many" bettas, I divide my largest tanks into as many as possible, providing as much cover as possible for each betta, to avoid them getting stressed from their neighbors... OR I use coroplast. Sturdy, though you could use a little silicone to secure the top. Then this way they do not see each other, however there won't be air flow from a filter throughout each section.
I think jars should be kept for breeders, and sick fish. Not kept permanently... Unless for some reason a betta has a chronic issue, like Chronic SBD, but then a shallow bowl would be a better option.
Sorry guys! I forgot to mention I sell them later, locally :P but I don't have a room that I can heat, except my edroom, which is okay in the day, but i like it 65 at night :P
I don;t want to divide tanks, because then whatever the disease is can spread. So yeah my main problem right now is heating... ideas? The floating in the tank idea is bad cuz I don't have anywhere to put a large tank, but I have a bookshelf for jars to go on.
When I need to hold a lot of fish, I take a rubbermade container or a spare tank and fill it about 4-5 inches with water, then put the fish each in his separate jar with whatever medications he or she needs and place a piece of plastic between them to keep them from seeing eachother. Like this.
As you can see, there is a heater in the back. the temp is a steady 78, and everyone has clean water.
