Red cherry shrimp questions
Having just returned from a 10 day holiday, I got home to find that one of my shrimp has disappeared. I'm not sure if it died, got accidentally sucked up the filter/gravel vacuum, jumped out, or *someone* got hungry...
On another note my Ambulia bunch had also vanished while I was away! It seems to have died off and all that was left was some measly stalks. I suppose it's possible the dying plant caused an ammonia spike and the shrimp died from that?
The one that have vanished seemed smaller than the other five and never coloured up (in fact it turned clear). I've also noticed that two still alive aren't really eating when I feed them, and the others aren't as active as normal. This has just happened in the last two days (since adding a new plant). I checked the water levels yesterday and all was OK.
A quick background on my tank:
30L glass aquarium, heated, filtered, gravel substrate, planted with hygrophila, bacopa, 2 crypts, java moss and now lace fern, weekly 25% water changes using Seachem Prime, test water every 3-4 days using API Master Test Kit, feed betta twice daily, feed shrimp once every two days (flakes and bloodworms), dose a tiny drop of Flourish once per week.
Anyway I have a few questions:
1. Is it normal to for shrimp to disappear?
2. Does molting also slow them down?
3. Is it possible to add new water too quickly to the tank?
4. Am I doing anything wrong?
Sorry for the long message, I'm just super keen to do the best for my critters!
