Ghost Shrimp questions.
So, today at the pet store I usually go at, they had a 10 gallon tank filled with ghost shrimp for $1.00. I bought 5, but, since I was the one that netted them, I got six by accident.
Anyway, I looked up Ghost Shrimp with Endlers', and found out that there is a type of fresh-water prawn being mixed in with Ghost shrimp, and will kill anything in the tank.
I also have 2 GS's with tiny black orbs in their lower body, and 3 of them are quite large, equal as big as one of my Corydoras.
My question is;
Is there a way to tell if it's a true GS?
Do I have two pregnant females?
Would they be able to live with male Endler/Guppies[I don't know which they are]?
Are they aggressive? I've seen my 3 largest ones nip at the smaller ones.
What do they eat? I have sinking Corydoras food, would that work?
Do they control Brown algae very well? I have an outbreak in my sorority tank, and the shrimp seem to enjoy poking through the gravel [which was obtained from my 75 gallon tank] and eating whatever it is they are.
If pictures are needed, I can provide them
