I'm in the same boat. Just burned through 3 Acro frags, the dragonfruit monti is holding up, and a 2 year acro at the top of my tank is still growing. Getting frustrated as well. I'll share anything I find on my end and hopefully we can all be successful soon
I feel for you too. But hey, at least you have a 2 year acro staying alive in there! Not sure if that makes it easier or harder to evaluate but at least until you find it, you have a coral to look at. lol.
