Thank you for the advice.
No I was talking about getting another Betta and bubble eyed fish (moor) in a 2 gallon tank. I would not trust my betta with another fish, since he has not been with one in over 8 months.
Is Bottled spring water ok to use? since that is what he has been getting for 8 months now.
What is a pleco? Do they help clean the tank out? would they be ok to keep with my male betta?
I am so sorry I am clueless about fish. I would love to know more about them, and I would be willing to buy some and have them shipped, if I can learn more about them
