Hello. I have a Betta fish, Chris, in a 2 gallon tank, no filter. I picked up "Chris", my betta, at PetCo last week, and he seems to be doing fine, very active.
Last night, I changed 50% of the water with a tube siphon. I noticed when I was siphoning the water off the gravel at the bottom that there was uneaten food and other particles mixed into the gravel. I managed to get some, but not all, of the particles out with the tube siphon.
My question is should I take all of the gravel out and wash it, or would this kill the "beneficial bacteria" which are supposed to grow in the gravel?
I'm thinking that in addition to a 50% water change with the tube siphon twice a week, perhaps once or twice a month I should take Chris out of the tank, put him in a small bowl, do a 50% water change, and wash all the gravel in a strainer under warm water to remove all the debris. Then return the same gravel to the betta tank after cleaning.
Does this sound llike a good idea? Thanks in advance for any advice.
