水草情迷

Sorry that I have to write this in English because it'll be faster

I have been an aquarium hobbist (different kinds of fish and grass) for years but just started to keep CRS in November last year. With the generous sale from other net friends I met here, I have been keeping 13 red and 2 black "S" grade crytal shrimps and all are growing in good condition (no casaulty so far) in a 14" x 8" x 8" tank. They are fed with bottled dried CRS food everyday. My tank is equipped with heater (21 degree), hang-on filter ("K" brand, 200L/hour), ADA red soil based with "SANG" stones, some volcano stones, one piece of "Mong Tu" stone, and Java moss. The water flow is just right. The in-water tube is covered by sponge. The only other creature is some "Apple snails".

Quite a few of them used to be pregnant (eggs seen in tummy) on and off. However, no baby shrimps have ever been seen!

Can any brother suggest why no successful breeding?

Thank you very much in advance for your ideas!

蝦B可能係太細仔, 你見唔到o者!

tiny carapace creatures like shrimp babies are very vulnerable to unstable water condition and too high temperature.
check all data such as NO2NO3 level, one hanged filter is no longer sufficient to entertain increasing number of shrimps. so try to buy one more 501 to enhance the water quality.

笙石同火山石都會推高PH喎!!!十一月至而家有冇check過PH?

I didn't check PH, I will do it tonight.

By the way, what is the influence of PH to breeding of CRS?

PH 越高 = NH4高
NH4 越高 = 毒性高
PH>7.5 不利水晶蝦生長
