Minimum tank size to keep shrimp happy?

[shaman]

I am using 1 feet tank. The rate of evaporation is very quick that I have to top up water everyday (about 10%). Water temp is about 26 celcius.
My shrimps sometimes will just die for no reason. I have 7 dead CRS in 2 weeks.
:(

Filter wise, I am using a small hanging filter. No water change as there are lots of moss inside the tank to absorb nitrate.

Do I need to upgrade tank to 2 feet? Anyone successful in keeping CRS in 1 feet tank? Thanks!!

i keep my shrimps in a small 1ft tank too and they do wonderfully, have u tried covering the tank top with glass or arcylic?? to stop the vapor?

what about water parametres? CRS are sensitive.

[imi_sky]

crs live just fine in there, even breed

I thought Shamans water parametres.

You top up water too fast..
PH & Tempreture change too fast..
I find that hang on filter not strong enough..

Upgrade bigger tank of cause better..


I had just setup a 1ft Ios tank with black soil..
Going to buy a 4 litrs wine cooler to run it as chiller..
Will update you of the out come.. ASAP

Ah, my water is slight alkaline, about 7.5. temp is 26. the evaporation is fast. i gotta top up 500 ml of water everyday (10%).

So whole tank is 5L? That realy small tank. I have also one:)
But its realy hard to get constant water parametres there. Mainly NO2, NO3, Amonia.

The water is just 12 litres... Ah! I am going to get one big one

I personally feel 2ft tanks are the minium for sensitive shrimps like CRS.

Of course those who cannot afford bigger chillers for 4ft :joking: is much better because I have a feeling my cherries are happier in a 4ft than the previous 2ft they are staying in.

Shaman,

I think you cannot generalise what is the minimal shrimp tank size, for cherry, I managed to keep them in 1 feet tank for quite long until population exploded. For CRS, with 2 trials, they couldn't make it in 1.5 feet tank, not passing 1 month mark.

IMO, the aim should be having them live for long time in tank, and not just a few weeks in a tank. It is not difficult to keep CRS to live in small tank for a short period of time, but I won't call it a success. Go for bigger tank. :)

Thank you. Do you know the reason why they fail in small tank? My bee and tigers are happy inside. But the CRS just cannot manage to cope in the small tank. Are CRS more sensitive than tigers?

Consider that a fish tank, in general, is an enclosed space, where organics (such as poop) accumulate. They dont' really have any place to go unless we physically remove it. I'm going to use a non-tank related example (just for fun) ...

Let's say we put two people in a closet-sized room (assume no door)... one person farts... imagine how fast the second person is affected. In fact, it's almost immediate and the other person will quickly cover their nose to adapt. lol :shocked: lol lol

Now, let's put the same two people in a 12ft x 12ft room, same scenario (no exit)... one person farts... the second person is still affected, but the smell has more space to spread out and the 2nd person has more space to run. :D

It's the same with a small tank, the effects of changes (e.g., temp, pH) are more immediate and more pronounced, simply because the space is smaller. The higher rate of failure has a direct link to the size of the tank. Taking a tank-related example... if you happened to put a drop of concentrated copper directly into a 1G tank, it will very likely kill every single shrimp in that tank. If that same drop were dropped into a 20G tank, you will still lose some shrimp ( probably the weaker ones), but some will be able to survive.

You must also take into consideration that not all shrimp are created equal. Bees and tigers may like the water, but that does not mean that the CRS will. There may be some suttle differences in the requirements for CRS v. Tiger v. Bee that you may not be aware of.
