My co-worker friend left for a month, and left a betta in a 5" wide bowl at her desk with no directions to anyone about how to take care of him. I'm glad I found this, did she think he was just gonna be fine for a month?? This poor guy's water is half empty (... lol, I guess that makes me a pessimist?) and completely murky. I don't know if his water has EVER been changed. He is living in poo. I gave him a little bit of betta food, which he ate, and now he's laying at the bottom of his bowl. i guess he's cold.
I've never had a betta, but I've read enough to know that these are miserable conditions. I'm going to fill the bowl (gradually, don't want to shock the little bugger) and then, later, I suppose i need to clean it somehow. In my online reading, people say to take the fish out, put him in some dechlorinated water, clean the bowl, put him back into new water. Does this sound right? Doesn't this completely get rid of any bacteria? How do these fish not die of ammonia poisoning?
Also, since I don't have any Prime or anything at work, do you think I can just use bottled water? Is that dechlorinated? My coworker said to put DI or milliQ water in there (I work in a lab) but I think the chemistry of those waters would probably be too different from the poo/tap water this fish is accustomed to.
Poo-fish and I appreciate any advice you have! Thanks!!
