    currently having a 2ft shrimp tank consist of (quantity in decreasing order) cherries, tiger, crs, malayan, green, bee, yamato, wood.
    intend to convert to crs tank. any idea how should i separate them out?
    my tank is packed with plants and woods, so would prefer not to shift a lot.

    hmmmm... I think you do not have much choice there. Use alittle patience and net them out accordingly. Unless some species likes a certain food that the rest wouldnt bother . Or perhaps draw them all out then makes its easier to sort them out?

    Why convert? Start a new tank for the CRS lar.... no need 2ft, jus a 1ft cube tank suffice for these precious ones....

    IMO, a CRS tank shld be as low maintenance as possible, best just tie some Java moss to DW with no CO2 and jus a small internal filter. that way, u will not have to worry bout algae, dosing fert, lightings etc etc.... jus on the lights as and when u like.

    i have started my CRS tank with erect moss and in less than 2 months, i have to remove the entire lawn as it has started to turn brown due to insufficient light hitting the bottom and also lack of nutrients as i was afraid of overdosing with fert and CO2. now have changed to Taiwan moss lawn instead as i haev heard of pple successfully keeping Taiwan moss in non CO2/dosing of fert tanks.

    What about throwing in some algae tablets in the open ground...it should lure them all out so you can net them while they are feeding?

    Truthfully, Mossana-Mossini, I once tried to do that; removing all my cherry shrimps from a 1.5 ft tank thickly planted with Blyxia Japonica and Glossostigma Elatinoides in dire need of trimming.

    I gave up halfway, and decided to do a complete rescape to the tank. Even then, there were quite a number of baby cherries among the gravel that I simply cannot spot. You can probably catch most of them.

    Even if you can draw them out using algae wafers, there will always be at least a lot more hiding among the leaves. My advice is don't waste your time, take this opportunity to rescape as well

    Good luck.

    any cooling system used? 'coz i dont want to put them at risk..... especially crs...

    the other consideration is that will the water chemistry (e.g. nitrate and stuff) harder to be controlled at 1ft compared to 2ft tank?

    i was using only one Profantec fan blowing 24/7 on my 1.5ft CRS tank. managed to keep the temp at a constant 28 degC. Yesterday jus added one more fan (as my new chiller had just arrived for my 4ft ) and plug it together with the lights. Will check 2nite whether can 2 fans bring the temp down further.

    a smaller tank will be more difficult to manage in the sense that any changes will have a greater effect due to the smaller water volumn. that's why keeping low requirements plant is a plus point as you do not have to worry bout CO2, nutrients and stuff. and if the tank is solely for CRS, then nitrate level shld not be much of a problem. for me, i just top up water due to evaporation everyday and make an effort to WC (no more than 15% each time) bout once every two to three weeks.

    I use profantec fan for my shrimp tank and it lowers the temp
    to 25-26C.

    fan will be sufficient, but evaporation is very high thus require frequent change of water not top up. Basically all crs found in Singapore is already climatised to our water and climate. It's because when u buy it at a shop or person the tank water is mostly cool or cold thus might crash with ur water at home.

    Afraid of water chem then use a bigger tank and use filter... else buy some water conditioner that removes nitrate and ammonia.
