I had 2 young Peppermints put in 2 weeks ago. The less aggressive one died 5 days ago, and the other died 2 days after. Fed them 2x daily. Water test fine, corals good....wondering if the frogspawn stung them? ...hermit and snails ok....I saw a 1" bristle worm(darker band in the center) crawling on my glass during the day yesterday....at least that's what I assume it is according to ID pics of them.
I feel like I have failed them. Never had problems with shrimps before in my other tanks....now I might think I need to keep working with a larger tank. Feel bad if I messed up, but don't know what I did wrong except a 10% water change might have shocked them.....which I do weekly.
