Wow, thank you guys. I know he's tight in the current tank, but I do try to keep him at least entertained. Thank you so much for taking the time to research it more, that was very thoughtful.
It's funny you mention the powerhead, I just this past week found and old one and got it running and have been using it for a few hours at a time. He enjoys it, and it ticks him off if it's "in his spot", the plants too, I have done that very thing, making mazes, when he was smaller, he loved it. Now he hates plants and attacks them. Goofball. He loves trying to tag the pleco, but she's way to fast.
Now I cleared out most of the tank so he'd have maximum space, he uses the entire tank, unlike my other Aro's.
I've been watching the tail chasing, half laughing, half worried, but figured the 150 would curb it. I do plan on adding a tankmate, still figuring out what to add. I want harmony, not 2 monsters fighting. The Zen theory applies to all of my pets, and they generally are quite content.
This Aro is getting better at interacting with me, he's not afraid, he gets into my business the minute I start working in the tank. He loves to be gently rubbed (2 fingers) at the end of his body (meat not fins), he developed dropeye and the change in his vision drastically altered his behavior 2-3 mos ago. It was like starting all over again. Now, I see progress again. He was afraid of everything. Now he's learned to handle the change.
I can't wait for my new tank, I'm sure he feels the same way. I think I've been duped by the people I was going to get the 150 from, so I ordered one from my lfs (359.00 just tank 6" long, 20" front to back, and I don't recall the height, but not too tall, which means I can reach the bottom for cleaning!
It's tougher to buy anything where I live it's pretty remote, long ways to a large city and most tanks come with a large shipping cost. Either way, I'm counting down the days!
Thanks again!Mei and Fu Man Chu
