i have a 8ft devided in 10 for 10 female bettas they are getting along perfect i have had them for 2 years now only 1 or 2 problems with fin rot wiht one of them but its been treated and that was a couple of monthes ago no problems then and yea 0.5 gallons try and get a bigger tank like about...
i used to have a tank like that it was not bad but it wasent big enough for what i had in there. now iv got a 8ft one with about 20-30 fish adding some more soon.
The tube is the worst ever iwould never keep a betta in a 3 or below tank i would only keep them in a 4 or above and iv only kept bettas in a 4 section devided tank and that turned out a good idea they have more than 10 gallon per fish sadly my brother turned the heater up when i was on holidays...
no one understands delete this thread please :( i just put then in. and i know the link was betta_246's cuz my bampas is exactly like that just black deviders.
Sry to say he is doing to die there was the same problem with a betta fish in the pet shop my uncle works in. he said they feel no pain but it is better to euthenize him. don't ask me how just if you get any more comments telling you hes going to die euthenize him.
Nice set-up i have a 8ft tank with alot of fish in there i did have bettas in there before i put my other fish in there my bettas died cuz my brother turned the heater up really high while i was on holiday when my nan come over to check them he was messing about with it so i got all new fish now...
