Just use a heating rod. Boiling water will make all the oxygen in the water disappear. It is not clear whether there will be more other things. Fish feed is mainly composed of granules and shrimp skin. Buy something good. Barreled shrimp is the best, and it can be cut into 50 barrels, which is the kind of eighty or ninety. Feed the granules, change the water frequently, the parrot can eat and pull, and change it in half in three days.

My parrot has been ill for four years, so I can't treat this disease. I can tell you how to raise it. I hope the landlord's parrot will recover soon.
