with a huge thanks to Soothing Shrimp on this site, i finally think i got the males i need for my chocolate shrimp colony to get underway!
unfortunately i think i lost one of my crystals because i disturbed the substrate too much. i tried to replant one of the blyxas (replanted into three separate plants) but the roots were so extensive that my replanting churned up too much of the deep substrate and probably caused some issues
NEVER replanting blyxa like that again. next time I'm just going to cut the pieces off w/o dealing with the planted portion.
