No gloves or masks, I'm sure I've gotten a bit of everything all over my hands at some point and I'm still alive! ;)
You can dispose of it down the sink as well. Or at least I always have, and even when I worked at an LPS and we used this kit thats all we did.
I saw one today, a beautiful teal/black color. But I was only there to look. And I still had my dead fishy in the tank waiting for my dad to move him because I'm too scared. I'm going back on Thursday hoping he is there!
