Better cause dont have to worry where to hang the adapter.....come with tank clips and braces...to clip on.

Expensive as compared to diy fans.(Which have to diy it yourself)

these are AC fans so no need adaptors. those that need adaptors are the DC fans which u can find in Sim Lim, u will need an adaptor to convert DC to AC.

So is that anyone here keeping shrimps without fan and is successful even to breed them? Thanks.

All Japanese CRS website recommend 25C to keep CRS, and they mentioned they have problem with CRS living in summer, and we are all summer all year round. You can keep CRS with a fan, it will not mate well, the hatch rate is low and infant mortality is high. You will end up with very few or no babies. Some more pregnant CRS needs very good water condition, warm water will kill them. CRS goes best with a chiller at 25C.

Why not use a translator to read Japanese website and just depend on hearsay? I wonder he breed CRS at 30C or he also hearsay?

i just bought one 5" AC fan from Simlim , about $11 , and plus one 2-pin cable ($1.8) , and that's it ... the fan is strong enough to keep the water cool (3ft tank, temp drop from 32 to 27 (during photoperiod) , non-photoperiod can get down to 26.

only problem is the water evaporation rate is high :\ but no choice la .. cant afford a chiller .. hehe .. so bo bian lo

since it's a low-cost investment .. why not install one fan first and see how's the thing goes ?
