UGH!!!! I feel like such a bad betta keeper!! :( Phantom passed away! and I have been doing daily/everyother day 50-100% changes to try to treat for fin loss, adding NovAqua+ which has aloe and echinachea and adding just a bit of Pimafix to each h2o change and WTH!! I am feeling very discouraged and I only have Firefly, Firedrake and Spartan left (and my friend's Betta). my 3 cory cats are like sooo Sturdy and I only have them in a little KK right now. What the heck again! I feel like I am doing everything right to. everyone, except for my friend's betta and the corycats, has a heater and they all are eating and swimming and Spartan makes bubble nests and urrrgh!
I don't understand why I am having so much trouble with them, it makes me want to cry, cus even though I don't have a bond with them like my other pets, they are all sooo special to me :( :(
I am not quite sure what I am going to do with all my fish tanks now that I have a few empty ones. I am scared to go get more to fill them, and then have THOSE bettas die at my obviously incapable hands :(
I might consider placing small sponge filter in tanks holding bettas ,and perform water changes twice a week of fifty percent while leaving the betta in the tank. At the four or five week mark, the sponge filters will have developed some good bacteria to help process ammonia from fish waste (poop), and food and after this bacteria has established itself, then one weekly water change of fifty percent will be all that is needed.
Sponge filters produce next to no current and should not bother the fish too much.
Would also call local water company for info as to whether the water from the tap is treated with chlorine,,or chloramine. if it is the latter, I would switch to water conditioner such as PRIME or AMQUEL+ that both detoxify the ammonia portion of chloramine that may be in your tap water. Many water conditioners only remove/detoxify chlorine portion of chloramines ,and bacteria in the filter are responsible for the ammonia portion of chloramines. Without a filter,, the water conditioner you are using is detoxifying the chlorine portion of chloramine if indeed tapwater is treated with chloramine ,but doing nothing for the ammonia. Chloramine is a combination of the two.
Would use conditioner such as two mentioned if indeed the tap water is being treated with chloramine rather than chlorine. Without such a conditioner, when large water changes are performed,, the ammonia from chloramines could be contributing to the problem.
Should you choose to try sponge filters ,just squeeze them out once evry couple weeks taking care not to clean them with tapwater but rather old aquarium water or dechlorinated water.
Hope some of this helps.
