I currently have a RBTA, I'm not exactly sure what the issue is, if there even is one.
Occasionally, the roots of the tentacles turn black but then they become normal again later.
The tentacles are not bubbly like they were when I first received the RBTA off of craigslist. The tentacles are now long and stringy.
The mouth is kinda white but I don't know if it's a bad thing.
I haven't spot feeded my RBTA until a day ago and I feel like it's gotten a TINY bit better but I have no idea.
Here are some pictures!
