Shrimps MIA

[PC82]

Hi guys, I'm a newbie in planted tank and decided to plunge in after reading this forum and researching on the net.
Recently, I had just set up my new 4 feet tank. After cycling the tank, I've added in 5 glass catfish, 6 small neon tetras and 10 CRS shrimps. The glass catfish are usually hiding and the neon tetras are swimming around most of the time. Initially, I can see most of my CRS swimming around the tank. After a few days, the number dwindled. From like 9-10 CRS I see initially, I see like 5-7, then 3-5. Then now I only see 1 in my tank. Then I think maybe they are shy, I go and buy another 10 cherry shrimps. And it's the same scenario again. From 9-10 initially, now I only see 2 in the tank. Then I decided to rescape abit of my tank, I moved some of my plants and rocks. Surprisingly, I don't see any of my missing CRS or Cherry shrimps. If they are dead, at least I think I should be able to see their dead bodies. This is really wierd.
Sorry for my long post, but I was wondering if any bros here had such an experience before?
By the way, recently, I went to buy another 10 Yamato shrimps. Since they are much bigger in size, I want to see if they will go missing again.

If they died, it only take 1-8 hours or less for his brother and sisters to consume him.
this can happen regardless of feeding, since their abit more sensitive to parameters then cherries and yamato chances of dying should be higher.

Glass catfish eaten them, like what others say, only fish that is shrimp safe, is oto. Even some pleco attacks shrimps. I doubt neon will eat them, unless its shrimplets, but even so, weakened adults might still be eaten or harassed by tetras

Initially I've also thought that it might be eaten by the glass catfish. But judging form their mouth size, it seems that it can't really fit in a CRS shrimp size that I have. Monitoring my yamato shrimp. Hope this time round, it goes well.

The corpse of the dead shrimps will be broken down within 3-4 days after death... Very fast.. Maybe can say 'melt away'.. So no surprise that you cannot find dead body..

Happy shrimping..

Trying seating in front of the tank for a period of time. You might be able to see what happened. There is a reason why fish are not ideal tank mates for shrimps. One reason is because they end up being food! I have personally seen neon tetras hunt shrimps in a pack in a heavily planted tank, so it is not a big surprise that your shrimps disappear one by one.

One of the usual mistakes that new shrimp keepers make is in thinking that because a fish cannot seemed to fit a shrimp into its mouth, it cannot eat the shrimp and is safe.
Many fish can actually "dislocate" or unhinge its jaw to open wider than it normally looks, allowing it to swallow a shrimp. eg. rams
Other fishes simply rip the shrimp apart into bite size pieces or bite off all the legs and parts they can get. eg tetras

I'm pretty sure ts haven't seen a bichir yawn underwater or an Oscar swallowing a hikari massivore delight in 1 gulp

How long have your cycled your tank with bioload?

About 1 week +

It takes at least about a month before the beneficial bacteria establishes itself in your filter and tank. While your tank is a 4 footer, it is still not prudent to place in expensive shrimps that are sensitive at the moment. Did you use any anti-chlorine or chloramine for your tank water?

It may also be prudent that you measure your NH, NO and PH levels.

my cherry/sakura shrimps are living happily with more than dozen of cardinal & neon tetra in a low dense planted tank and its population keeps growing. maybe it will grow much faster if without those fishes.

Yup, I did use anti-chlorine and chloramine for the tank water. Planning to measure water parameters soon as well. Guess like, I'll have to re-plan my tank inhabitants.

All you need is time for the tank to establish. I don't see anything wrong with the inhabitants you have...just that I think Glass Cats Do get to quite a size.

Yamatoes are greet algae eaters but I do not know how they will react with other shrimps. I don't think Yanatoes are aggressive though.
