Sorry I'm new to the site, I just found everyone's replies and questions. Thank you by the way.
This is probably my 10th aquascaped aquarium so if I don't answer every tank parameter question, please know the only thing new to me is actually owning the shrimp. It took me 4 months alone to locate a breeder that could meet my demands.
That tank is on its 7th month, all of the carpet plants were grown from seeds and the other plants are clipped and cloned from one of my other tanks. The water is within prime levels from Fire Cherries, that took a couple months to get right. I wanted it to be perfect since only Cherries are going to be living in that tank. Rift to Reef supplied all my products and walked me through the "species specific tank" set up, but over all, it has 7 months worth of cycling and prep for Cherry shrimp. As far as feeding, I only feed them bug bites every other day and even then only a pinch. There's plenty of bio film and algae on the edges of the granite. I was afraid overfeeding would promote hiding or just chilling out in a hidden spot. I wanted them to be actively hunting for food or scavenging and the 1st couple days they did, they were all over, extremely active. It's 8:00 p.m. now and I've been in and out checking out the tank since 7:00 a.m. as I do the light cycle spending sometimes up to half an hour sitting and watching. Today I have yet to see a single one.
The picture I attached is zoomed in quite a bit. He's only half an inch at most. I know they don't live that long maybe a year and I specifically asked for juveniles So I'm hoping there's no reason to believe they're dead. I think the only thing I never bothered to ask is if they dig burrows and hide. However my carpet plants are pretty thick and their root system is visibly thick as well, when seen from the outside glass of the tank. However I know there must be a place they could dig if they wanted to I just don't know if they do. If they had all died overnight I would hope, 1 the problem would be more obvious being a covered tank there shouldn't have been any contamination and 2 shouldn't I be able to find a body if they all died? No sarcasm, these are all questions that come up as you go. As hard I I tried, I couldn't prepare for everything.
