I had a LTA for a while before I had lighting issues, it was such a hardy little fighter, spent like 3 months with no light. It was weird because it only died after I fixed the light....I cried for it....Nemo did too
It was almost too easy to take care of and I had no experience, I know I wasn't the best caretaker but somehow it was thriving up until the light failed. I fed it a piece of shrimp the size of my thumbnail about once a week and it doubled in size but it didn't come close to outgrowing my tank. And while I'm sure it'll outrage everyone, I'll admit to hardly ever doing water changes or checking the parameters. I have a 24g nano and I had 1 ocellaris (Nemo), 1 neon goby, and a massive cleaner shrimp along with the LTA. It bedded down in the back right corner and stayed there.
I recently purchased a BTA that was
huge (I don't know what I was thinking and took it back 2 days after I got it). But I had a completely different experience with that. First it spent the whole night rolling around my tank like tumbleweed and always seemed to land itself face-first into my frickin' mushrooms.It took up the entire back corner when I placed it there to get it out of the way in decent space. It expanded to a massive size de-homing poor Lenny the Blenny. He bullied is way into Goby's home and I couldn't find Goby for several hours which had me in a complete panic. I bagged the anemone and returned it the next day.
Thats just my experience
