Good info, thanks. I have some updates and a question.
Update 1) I've noticed a few molts in the tank and think I know which shrimps have molted, three of my shrimp seem bigger and much brighter than before. I take that as a good sign.
Update 2) last week one shrimp was carrying eggs, yesterday I confirmed that a second one is also carrying eggs. I think it's considered an orange rili, its orange but with a clear center. Crossing color types might be frowned upon but I'm keeping any offspring for myself, these won't make it to any shops or anything.
Update 3) I added a few more plants, interestingly all 4 of my orange shrimp are drawn to one particular plant, it's a ludwigia. They seem to feel sheltered there but I'm a little concerned as they've lost their lust to explore the rest of the tank. They just chill out looking content to hide in the ludwigia. Is that normal? Making it more interesting, my 2 newer red shrimp have no interest in the ludwigia at all.
Update 4) I have snail eggs. Ehh lol
