Never use ice with chams. You stress them out by dramatic change in temps. Just poke a tiny hole in the bottom of a cheap plastic solo cup. When poking the hole you don't want to go all the way through just enough so it barely drips.
They are, I'm pretty disappointed but they're hard to sex so it is what it is. I know there are few people who have several pairs so I'm hoping maybe someone will want a new mature male.
Bought a pair of Parson's last year and it turns out that I have 2 males. Seeing if anyone has a female they may trade or perhaps to breed with one of my males.
