Hi everyone! I'm usually lurking on the website, but I'm a big fan of this forum and the great information it has. I hope this helps express my gratitude to you all! I recently wrote an article on shrimp macro photography for Photography Life, and they published it! I hope you enjoy :) https://photographylife.com/aquarium-macro-photography-of-ornamental-shrimp

A trick we use to cull snails is to leave a fish net in a bucket of aquarium water. Outside if possible. Few days later the net will have a nice biofilm on it. If the net is then added to an aquarium, snails will swarm all over it. Net can then be removed, the snails shaken off and the process repeated. Perhaps netting would be a good medium for growing shrimp biofilm food?

I think the parents are yours from south east of Melbourne. You need to remind me of the location so I can write it down. The others I have from western Vic are young and have not saddled yet (but getting close).... but they are mixed in the same tank which is not ideal but with all the other native shrimp species there's only so much room for Paratya.

About 3mm in length. The light flecks in the water is the best timed green water outbreak I could have wished for! The green colour of the body suggests they might be eating it too so its all fingers crossed for some post-larval juvenile settlement.

O cool, they are from where Dandenong creek goes through Bangholme. You've proven that population has a planktonic stage. Was it a salty green water mix you have them in? Did the western Vic ones end up getting much bigger, they were quite small when I saw them. ive got another 3 types of paratya I'm waiting on to see how they breed. Plus a c.indistincta and another little group I've just collected from qld which I haven't had a chance to even see what they are yet, but they do have large eggs.

Stunning photos! Read your article and checked out your website. Very impressive photos, not only limited to the shrimp related ones. Welcome to SKF and thank you for sharing.

Wow. Amazing photo's and a really good article. Welcome to the site.

The answer to both your questions is likely yes. Biofilms begin to form immediately once a surface becomes submerged in water. When a tank is set up, there are lots of nutrients released (from the substrate, from plants and mosses that are stressed due to being moved, ect.) so the biofilm can use these nutrients to grow well. At 4-6 weeks your tank would be cycled, so safe for shrimp, but still have a good layer of biofilm because of those nutrients during the first few weeks when the aquarium was cycling. The best way to answer the second question is: Imagine biofilm is like grass and your shrimp are like cows. If you have lots of cows in a paddock, the grass is eaten away. If you have few cows in a large paddock, then the grass gets a chance to regrow before it is grazed again. It is the same with shrimp. Shrimp are grazers and will reduce the amount of biofilm that is available through heavy grazing pressure.
