rotifer culture with semi unexpected artemia

Thanks for the corrections!

 

yeah... my bad

 

That's parameter dependent really. If the conditions favor the artemia, they'll eat more... salinity and temp would be the two to elevate to have your artemia out compete the rotifers. Lower temps and salinity will help the rotifers out compete the artemia. They come from pretty different environments.

I've co-cultured them together just for fun, but I was using a much smaller species of rotifers that favor higher temps.

Artemia molt, that decays and the bacteria becomes food for both artemia and rotifers. The downside is the extra poop and debris tends to drop the pH, which adversely effects the rotifers.

 

my pleasure. Gotta put that info to use someplace in my life, 99% of the times it just sits there taking up space

It's actually part of my day to day job though - I work for Reed Mariculture (Reef Nutrition/APBreed/Isntant Algae/Etc)

 

interesting, iv read ideal salinity is 1.017, mine is currently round the .020 (my DT is 0.25) and temp is 26°C.

 

For hobbyist, this is what we recommend:

Salinity: 10-35 ppt (S.G. 1.0075 - 1.026), optimum 15-20 ppt
Temperature: 27°C/80°F (L rotifer type); 30°C/86°F (S rotifer type)
pH: 7-8 is optimal, 6.7 min, 8.5 max
Ammonia: Maximum 1 mg/L NH3
Optimal Feedings per Day: "Continuous" feeding (~ every 3 hours)
Minimum Feedings per Day: at least 2x per day for good production
Harverst Rate: 20 to 30% Daily

 

Swiss, have you noticed any more batches of eggs or are the clowns engaged in nesting behavior like getting ready for a clutch (I think that's the term) lol if I'm way off on that

 

Unfortunately they have not. But im confident they will again
