It was bare, but not totally. I helped them choose decorations at one point and did recommend the silk plants, which is what he had in with him when I was up there last. I'll be stopping in again tomorrow after work -- he had pretty bad SBD so I decided to focus on that, and since water changes would be upped I thought it might be easier for them to keep just the one plant for now. It's a fair-sized plant.
Unfortunately the tank he's in isn't very large...it's one of those decorative "Brandy sniffer" "tanks" from PetSmart, or whatever they're called. I believe about 1.75-gallons. I had strongly recommended one of the 2.5-gallons with a glass canopy or a large Kritter Keeper if they wanted to keep the price down, but I think they then decided to go for something "prettier."
I'll be checking on him again after work tomorrow and see how his SBD is doing, which is my primary focus since he's not moving much because of it and I think mostly resting on the plant he has. I'll have more time than my last visit to talk to them about things, and hopefully his primary caregiver will be there then as well. I actually have a day off coming up soon, so I can even go with them if they decide to pick up anything new for him. Maybe I can even convince them on one of the new Marineland 3-gallon Crescents at work since they're on sale right now, so they're not a bad price and attractive but not that large if they want to stick to something smaller.
Believe me, I'd like to see him in something larger and more decorated myself, but I ultimately have little control here but to help them along, which I am trying my best to do. They do care about him, but it's still a learning process for them, and the person who takes care of him most isn't often there when I am.
