Ammonia - 0
Nitrite - 0
Nitrate - 20
The tank is 10 gallons and has been cycled for about 2 months
Filter - whisper in tank filter 90gph
Water changes once a week, about 40-50%, I use amquelplus water conditioner
The only inhabitants are a single male betta and a black mystery snail
The only thing recently added is a live plant - I don't know what kind it is but it was properly QTed and betta was a little sick before I put it in
I feed the betta blood worms 3 days a week, betta bite pellet things 3 days a week, and nothing on 1 day - the snail gets sinking algae wafers.
I hope I didn't leave anything out. The problem is that over the past few days my betta has been spending a lot of time sitting on the bottom. He only perks up and swims around when I come up to the tank. He looks so unhappy
Thanks in advance for everyone's help!
EDIT: oops, forgot pH is 7.8, it has always been the same, no crash or anything.
