My Own Shrimp Breeding Problems

[talldutchie]

In my experience optimal breeding temp is 25c which is... err...77F.
Splashing them around is not something shrimpe enjoy because they're not that big on swimming so stopping that is probably a good idea. Use a plat or, if possible, put the bucket above tank level and syphon it in.

The temp on the 2.5 is about 74 degrees fahrenheit, and the temp on the ten gallon is about 76.
pH is=n both tanks is 8.4. Yes, it is quite high.

Temperature range you have them at is fine. pH is high. You could help lower pH naturally using peat moss, a large chunk of driftwood, or using ro water. There is that ideal temp and pH range you want to keep rcs at, when you get to the extremes of that range you issues with them breeding.


To avoid causing too much chaos when putting in new water, in the smaller tanks I'll hold a small plastic container or bowl in the tank and pour water into that.

I use a colander over the tank when filling. It's a gentler way of adding water.

Nice idea, never thought of that.

I've had no issues whatsoever in breeding them in the ten gallon though, but do you think the high pH is just slowing down the breeding process in the 2.5? Causing them to lose more eggs early on, coupled with the stress of pouring new water in abruptly every week?

I think it's a combination of those 2 factors. I think pH 6-7.5ish is the range most sources mention. There might be a long term effect at keeping them at too low or too high a pH.

I use an airline tube with a gravity feed from a large water bottle... Its the most non-intrusive way but it takes 5min

Perhaps, but is it safe to put peat moss of other pH lowering devices (not chemicals) in a tank that small? I'm glad that I believe we have touched on the cause

[aquariumlover10]

it maybe a problem with the temp or there aren't any males in the tank.

I thought heater might be an issue :\ but my shrimp actually bred in December, and have bred probably 4 or 5 times since then! I must have been impatient. Plus, the collander thing seems to work really well too :)
