my girl doesnt know it ....but slowly im training her! down the road..she'll know everything i do(almost) when it comes to my tank. I'm pretty sure i could tell her over the phone how to do anything/everything for my SPS dominant tank
My girlfriend can do some of the basic things on my tank when I am out of town. She feeds the fish, refills the ATO, acclimated some new additions I had shipped in, and pretty sure she even changed some filter socks for me once. She won't admit it but I think deep down she likes my tank. Don't say that too her though because she can't get past the money I have invested in it lol.
I try to keep her somewhat involved by trying to let her pick out some corals or fish for the tank but for some reason she has a taste for things that don't play well with others
