If they can get to the rim of the tank, there might be a chance that is a problem. If not, look else where for the issue (predators...water conditions.).

I've more leaves in my tank!
Anybody tried this before? Especially yamatos! All my yamatos died outside my tank! Is it the water parameter stressed them out? or they are juz jumpers in the water? Cuz i was using HOT filter last time, water level has to be kept high to prevent surface disturbance.

If you see them crowding at the filter outlet, chances are they don't like the water parametres. They can also be spooked when the lights switched off suddenly.

Will chinese algae eater and golden algae eater harrass yamato? Seriously i dun think its the water parameter, all my yamatos are found dead outside my tank on my floorAnd also they seem so happy in my tank. Swim here and there, nippling the algae on my foreground glosso. Another possibillity should be the lighting thing. Cuz i operating with auto timer. So sometimes when the lights auto switch off, i was giving a shock too, what about the fauna!
Anyway, thanks Peter and Fei Miao for the reply. Cuz i juz wanted to see whether forumers have the similar case as mine!
Hi,
I bought yamato on three occasions and each time they are found all over the house. Strange thing is that they don't jump out during the night when I do headcount. They only do so when I am not around. Maybe they missed me.........

It's your water parameter. I've kept yamato for a while now and none would swim to the water surface for any reason except to catch some fish flakes or to sieve for cyclopeeze if I am feeding the tank with it. My water temperature for the shrimp tank is kept at 25 degrees and it will only go to 27 degrees until the chiller kicks in. There is a part of my moss wall that is well above the water line and is easily for the yamato to climb on it but they have not tried it. This tank is also occupied with cherry shrimps with some fishes as well.The tank has 3x24w of T5 lighting. They are not spooked when all 3 bulbs are switched on at the same time. Believe me, T5 bulbs are bright.
The only problem I encounter is the house lizard perching on the moss wall that is above the water line. This house lizard has been feeding on my cherry shrimp for a while and has grown fat. It is difficult to catch this little bugger.

It is possible also that there was a lack of oxygen dissolved in your tank. If bioload is high and there is no surface agitation of the water surface at night, then your dissolved oxygen may drop to very low levels during the night. The yamatos will then hang around the water surface. Then the probability of them flicking themselves out of the water is higher.
Anything that spooks them will cause them to flick their tail, propelling them backwards at high speed. This is probably how they got out of your tank: they "flicked" themselves out.
My friend, who is a professional aquatics inspector and leading expert, says that if there is a current, often shrimps will then believe there must be an upstream and a downstream, and therefore further food opportunities on the other side of the glass. They're natural explorers, apparently. Best thing is don't give them the chance to get out. I lost three, but the other two are still there since I made the top more secure.
Wow u revived a 7 yr old thread
Ha ha, yes it's called the Frankenstein effect! Brinning threads back from the dead.
I googled shrimps jumping out of tank and found this thread.
Normally this won't happen...
Unless your water isn't right somehow...
most probably they felt threaten. by predators maybe? my ghost shrimps in my puffer tank always commit sucide instead of being eaten. use a cover to cover the top.
Shrimps will always try to climb in places where there is water flow. People who have HOF with outlet inside the water will see them hanging around there often.
Very rarely shrimps climbing out has anything to do with water parameters. If there is something wrong, they will instead get frantic and you will start seeing dead bodies.
