betta acting strange

Temperature

Is the tank heated?

Contrary to popular belief, bettas are best kept at a steady temperature of 78F and therfore really need a heated tank.

If the tank is not heated then you need to check the temperature. If it's below 74F then that could well explain sluggish behavior.

Also, depending on the tank size, you may need to change a larger percent of the water weekly. If it's under 3gal. I'd change all of the water weekly.

Agreed Littlepuff.....except if the tank is filtered then there really is no need for a 100% water change. It actually only serves to stress the fish. With a filtered tank you can easily do a 50% water change weekly, leaving the betta in the tank and gravel vac'ing at the same time.

put the betta in some bettamax. this solves just about all of my betta problems. hwat is the tank size? is the fish alone or with other species? what kind of filter is it?

i have all of my bettas in 1 gal storage containers. i change the water twice a week and siphon every other day.

you might also try putting in some live food for him (i assume its a him)to chase (i use guppy fry.)

your betta could also just be getting old. if you bought him from the pet store, chances are-it was already about a year old and his time may be coming.

if the snail is a recent addition-it might have been carrying some disease. take the snail out and add bettamax. does the betta seem to look different physically? how long have you had the betta and where did he come from?

the fish is fine now? im glad if thats what you meant!
wal-mart a year ago? sorry to say but his time will probably be up soon

his friends betta died last night when she was asleep
