Betta sickness

[christina9779]

Help!!!!
I always have Betta sickness problems and I don’t know how to solve them. I buy a healthy Betta, put it in its 10 gallon tank, I have a sponge filter going speed not high only a few bubbles.
My Betta always end up with sickness and I don’t know how to save them even if I do get medicine for them they still end up dead. It makes me quite sad. Can anyone tell me what I could do to save them so I have a future reference. Betta gets cotton mouth, ick, those are basically the two.
I feed them twice everyday change water 10% every 2-3 weeks, nitrate 0, nitrite 0, ph 7.5, ammonia 0. Light goes off at night and on in the morning. Temperature 77 degrees
I feed them only flake food and pellets no live food because I am afraid of germs on them. I don’t breed them just a hobbyist

The following link has info about what to do if your fish gets sick. It's long and boring but worth a read. I recommend printing it out and reading it in bed to help fall asleep.

Ich/ ick is a protozoan infection that is introduced into your tank on a diseased fish or contaminated water. It appears as small white dots on the body and fins. The following link has info about Ich (whitespot). The first post on page 1 and second post on page 2 are worth reading.

Cotton mouth can either be a fungal or bacterial infection and normally occurs on fish kept in poor water quality. If the fish develop it within a week of you getting it, then they have the problem at the pet shop.

------------------------
You need to do bigger water changes more often. I recommend doing a 75% water change and gravel clean the substrate once a week. The big water change helps to dilute any nutrients and disease organisms in the water.

Feed the fish once a day and vary the diet.

Post a picture asap if a fish ever gets sick.

As Colin has said, more frequent and higher % water changes. Do you have any thing else in the tank, plants, substrate etc?
Try frozen food, you don't get the risk of a bad batch and if you feed pellet do you soak?
