I'm putting together a first-aid kit for my Bettas, and I'd like some advice on what to stock it with. What do you keep on hand for emergencies? What should I avoid when dealing with bettas specifically? I have nerite snails and I might get shrimp in the future, but I have a small tank with it's own filter and heater to use as a hospital/quarantine tank, so their sensitives don't necessarily need to be a major factor. ...though medications that work for snails and shrimp might be a good thing to have on hand, too. I know the best first treatment for most fishy ails is a water change, and don't plan on jumping into medication without being certain it's necessary, but I'd like the security of knowing that if something does go really wrong really fast, I have good treatment options on hand.
