i got up this morning and noticed a flash of white at the bottom of my tank. it was the belly of my 8 inch silver aro. it was perfect last night. its barbels were doing great and his/her tail was bright red. The water was good. he/she has always been a picky eater but wasn't starving. i dont feed shrimp that could potentially have those spines. eats hikari and full spectrum. i did a 10% water change a couple days ago maybe that was it? the other fish are fine.
what gives?!?!
i know this comes with the hobby but i was shocked with this one. thanks for reading, i needed a nice vent.
edit: trying to solve this mystery. tankmates are 3x 5''ish plecos, 4x 5'' bichirs (3 senegal, 1 delhezi), and 1x 4'' sun cat. they live in an established 72 bowfront running a fluval 304 and rena xp3.
