While I've never owned a fish myself, I've been reading about establishing a tank and fish care for about a year now. I still haven't made the leap yet though as I want to do things exactly the right way and have a happy and healthy fish (mostly likely ONE male Betta fish), and right now I don't have a lot of extra time.... However, coincidentally, it has come to my attention that my sister-in-law has one male Betta fish her school principal dumped on her last year that she couldn't care less about. I don't know how this poor, poor, poor fish has survived so long. I don't think the container is bigger than 1, maybe 2 gallon(s), ans she laughs about changing 100% of the water only every 2-3 weeks. Btw, I saw her change the water the other day and she scrubbed the plastic container with dish detergent before refilling it with tap water without treating it with conditioner; she denied it, but I saw her pour the water straight from the faucet and drop the fish back into the container, so what is there to deny. Obviously, no filter, no heater. That "tank" is next to the front door with terrible drifts, even though I mentioned to her twice that Bettas need to be kept in warm water.
That fish is in very bad shape; he's just a blob barely flotting at the bottom of the tank above the gravel. It breaks my heart.
I don't know how old he may be (I'd say close to 2 maybe?), how bad his health is, and how much longer he has to live.
Is it worth for me to invest in setting up a new tank right now?
In this specific case, could I use these products they sell to speed up the cycling of tanks?
Ultimately, would the 1-hour car travel stress him even more? How would I acclimate him?
I'm sure my sil wouldn't mind getting rid of him. But it would suck for me to put all this hard work and have him die on me; I know my 3 year old would also be heart-broken if we take the fish in and he dies!
Would love to hear your advice!
