Hi Slief - May not be related but I was going to say that in one of the videos you recently posted I didn't noticed the RBTA. Was going to ask. Anyway - maybe this is why I didn't see it.
I have 6 of them with the oldest being a little over 6 years old. No idea why they do what they do. Some say stress, others say feeding. Tank is fine so unless the stress is from the mated clowns fighting all the time I couldn't say. Mine also do not have bubble tips. Some say flow, others thing otherwise. No idea and I do not directly feed.
I will say that mine originally started in a 29 gallon bio-cube. Split, and 29 gallons didn't seem like enough. On the third split I felt I was definitely out of room so moved one to another 29 gallon. Mistake. That one split

Later during a move merged the two tanks into a 40 breeder and it wasn't too bad. More splits so it is upgrade time again. This time 240 gallons and that is it. If they decide to split anymore I'm going to start giving them away because I can't upgrade past this
Looks good in the 'fuge though. Nice photos and overall tank/job
