Amano Jumpers

[colinsk]

I guess two of my Amano shrimp could not stand it anymore. They jumped out of the tank. I onlt have small openings and I can imagine how they found an opening or how the managed to get out. I found them on the carpet today.

0 Ammonia
0 Nitrite
0 Nitrate

Is this common?

First off, close the opening.

It could be from some water problem. Do you have more shrimp? If so, are they constantly swimming, without resting? If so, you need to do emidiate actions to fix your tank water.

However, Amano shrimp are crawlers. They do swim, but they also walk and climb about in the tank. I've not had any climb out of my tanks, but it could happen. Crabs and crayfish, and some snails are the most common escape artists.

They seem to be constantly feeding. They don't swim often. I have 8 left in that tank. Everyone seems to be happy. I measured the nitrogens and they were all 0. My plants consume all of the nitrates.

Are there other water parameters that I should worry about?

gH 5
kH 4
pH 7.4

I've had it happen and heard of it. it's not uncommon in situations where the shrimp dislike the environment or are stressed by fish or other inhabitants. I've seen shrimp climb out, but also jump out by accident when startled or attacked.

I have kept amanos in a rimless/topless aquarium for almost 6 months and i haven't had any jumpers *knocks on wood*

Sure, ammonia, nitrates, nitrites, phosphates, metals, (copper in particular).

Again, make sure that you've plugged the hole. The point is having an aquatic Alcatraz, albeit, a nice one.

I think I have a clue. I never get to watch the tank in the mornings. This morning I sat for 30 minutes and all of the fish, snails and shrrimp were in the top 2" of the tank. Since I am so heavily planted the plants had scavanged all of the O2 in the night. I changed the powerhead to break the water surface. Within 20 minutes all of the animals were back to there normal locations in the tank.

Yay! - if only more people would spend some quality time just looking at their tanks...

The plants aren't scavenging O2...they absorb CO2 and release O2.

When there is light that is the case. At night they resperate and take O2.
