View Full Version : Creek "Shrimp"?

04-07-2013, 11:42 PM
I have a fine net and went into my local creek. It is very wide but shallow in many places. I pulled the net through the water very swiftly and saw that there were small shrimp-like lifeforms or aquatic insects. They were about 1/4" long, and looked like some short of insect shrimp.

Does anyone know what these could be? Are they good for fish food?

Never heard of a shrimp that lives in a creek, but someone may correct me.

take a picture next time your out to really verify it.

but here's what i think you saw-maybe infant versions

Possibly infant crawfish, yes.

Or if they have the tendency to lie on their sides, try looking up gammarus

Gammarus does like like those, however they seem to have a dorsal shield-like shell structure.

A pic would help. Knowing where in the world that creek is would also be a bonus.

cories are unable to eat something as big as gammarus.

In Australia a clear shrimp called glass shrimp can be caught in creeks and rivers

This creek is in Texas, about 10-15 miles from Houston.

My camera is so bad that I don't think you'll be able to see it clearly in the photo. Looks like I'll be getting a better camera soon :P

Which makes something from the gammarus family the most likely shrimp. http://en.wikipedia.org/wiki/Gammarus

Ah, true! I do see a few photos on Google Images that look like my captures. Are these freshwater amphipods good for cory cats and/or easy to breed?

If they are indeed gammarus, then I don't think that they would suit being cultured. Most species require very clean, flowing, well oxygenated water. If a Cory could catch one it sure would be a treat but my observations lead me to believe that gammarus are way too fast for something like a Cory and also will quickly grow too big to fit into a Cory's mouth. If you have any larger sight predators though such as larger characins, minnows, and cichlids, they probably will have a lovely time chasing down the gammarus.

if you decide to try it out.

probably should check your local laws-some times this stuff is protected species or endangered in certain areas. things like that come with hefty fines if caught.

So if I culture bloodworms and/or mosquito larvae, would that be a good source of protein for my corys? I understand that bloodworms sink to the bottom naturally, and mosquito larvae naturally float, but do cory cats enjoy these live foods?

04-10-2013, 12:25 PM
Bloodworms maybe, mosquito larvae would be a difficult catch. Have you considered giving microworms a try? My pygmies love those.

04-10-2013, 05:53 PM
So just throw out the mosquito larvae that do appear, or keep them to sell?

Give it a go at least once or twice, see if they manage to get at them. Worst case tip the bucket. Mosquito larvae tend to dive to avoid danger but spend quite a bit of time at the surface. Cories aren't that good at getting food from the surface.

I stick buckets of water outside now and then, then nab the skeeter larvae for my fish. I've seen cories nab the bottom-hiders, but usually it's my others that get them. If they think they're in a lot of danger, skeeters hide on the bottom a lot, so just kind of look scary at them and they dive.
