You may recognize me from the baby betta thread. :/ Anyway... So I have all of my 6 bettas on my kitchen table, and I will probably end up putting a tank or two in my room. (They are all adults). One has fin rot, one has septicemia and swim bladder disorder. I want to give them all an upgrade... meaning a tank of 2+ gallons each with filters. I'm only going to worry about adding heaters after summer is over. I'm thinking I'll have to use 5-10 gallon tanks with dividers with 2 fish in each tank. Just a heads up, I haven't checked any tank's ammonia or nitrate levels. And I do about 25-50% weekly water changes in all of the filtered tanks and usually full water changes in the unfiltered tanks. Also, I have found that a gravel vacuum does not work so well in 1 gallon tanks. Oh, and I have switched 5 out of 6 of them to Hikari pellets a couple days ago, which they seem to enjoy. What I need help with is filter and tank recommendations and additional care/cleaning suggestions. Here are the details of each of my betta's tanks and health: Sonny- He is one of my two males is in a 2.5 gallon tank with the TOM mini internal filter, so he's doing pretty well. The tank has not cycled yet or is at the very beginning. I am choosing to start the nitrogen cycle with him in it. He has a moss ball that he likes to rest by, but I would like to put some sort of hideaway in there that he fits into and is not sharp. Any suggestions? Ziva- I just moved her into an uncycled 1 gallon tank with a filter. I put about a 1/2 gallon of her previous unfiltered tank water into her current tank (I believe the filter has some beneficial bacteria from previous use though). She seems to be happy and healthy. Leslie- She is in a 1 gallon filtered tank. The cycle started over almost a month ago when I washed the entire tank and gravel. She seems to be doing well. Toby- He is in the same type of tank as Leslie. But I had a plastic plant in there and I think he did cut his fins on it. Of course I've removed the plant by now. Not absolutely sure on that, but he somehow has fin rot. It took me awhile to notice, so it has become pretty bad in his tail area. His behavior seems normal, maybe just a little more lethargic than usual. I did put medicine in his tank and unplugged the filter so it wouldn't absorb it. I think the medicine is mostly gone and I plugged the filter back in. I will be giving him some almond leaves and/or higher quality betta medicine very soon. Stella- She has had it the roughest out of my 6 adults (and the only one from PetCo-- go figure). I didn't know that I could help alleviate her swim bladder issues with medicine, so I recently gave her some powerful medicine to alleviate that and to alleviate her septicemia/red streaks on her head and body. I am weening her off of the meds and giving her something of higher quality soon. She's been doing the best she has been in months. But unfortunately, she is in an unfiltered 1/2 gallon tank. Lana- She is in the same type of tank as Stella. I had put her in the same tank as Ziva a couple months ago, and they hurt each other but not severely. (That was when I figured they would get along when I thought my 2 female babies were getting along). Needless to say, I've learned my lesson and they were together only about an hour. They seem to have be recovering just fine. Even a little bit of help is appreciated. Thanks in advance.
