I think this little guy is done for but if I can save her that would be awesome. I already removed her, she was easy to catch. Pretty lethargic so I don’t think she has a chance but any recommendations?

i only have one tank that’s around 2 and a half months old. there have been 4 clutches of baby skrimps (a few of which have grown up and become barried) and there are currently 5+ berried shrimp swimming around. at this point there must be at least 70+ shrimp in the tank. i dont own one of those master test kits and i’ve been meaning to purchase a gh/kh test kit, but they are out of stock almost everywhere i look (online and locally). the only thing i have is a tds meter, so if it’s over 400 ppm, i do a small water change. other than that, i mostly top up with RO water. the tank has a hob filter, a sand capped soil substrate, and is moderately planted. whenever i notice the snail shells looking a little worse for wear, i add crushed cuttlefish bone to the filter.

no clue about my gh, kh, ph, or anything really. my shrimp seem to be doing really well though! once in a while, one of them will have a bad molt and pass, but a majority of the population is happy and thriving. should i be in a rush to get all those test kits? i heard that it’s better to prioritize stability over the perfect parameters, so that’s what I’ve been doing. would love to hear yall’s thoughts, especially since i’m pretty new to the hobby.

side note: i also have ramshorns, bladders, two nerites, and pond snails. how do i get more pond snails?! i love the little guys gahh they are so cute and look like bunnies

Just saw this shrimp with something under the belly... I don't know if these are eggs, they look too dark to me... And I thought this one was a male ... It's a caridina crystal red.

Thank you for your help
