Hello everyone. This is my first post. I've kept larger tanks in the past, but this is my first small tank - 1.5 gal with a very small Whisper filter and one Betta fish.
I'm guessing that smaller tanks need water changes more frequently than the larger ones I had before.
Basically I'm wondering how often I should change water, also considering the filter. I don't plan on there being any uneaten food. I'm hoping to find a smaller siphon to use to clean the rocks and do a half water change at a time. I don't want to remove and scrub everything as some people suggest. I feel like that would just kill the good bacteria.
Also, the fish store owner told me to only feed two small pellets a day. That seems like such a small amount. I was thinking maybe 2 pellets twice a day.
Thoughts on feeding or frequency of water changes?
