ghost shrimp vs RCS - who is bigger?

The pictus is 5+ years old but I don't know how much growing he has left.

Again, just an experiment. Based on early observations the pictus is less than interested in the shrimp and vice versa. The shrimp have no problem strolling around in the open.
 
I had 3 ghost shrimp originally when I bought them. 1 tried to molt back when they were in my 10g and he didn't have many places to hide... the other 2 ate him. Those last 2 have been with me ever since though. I have caught one of them with a pond snail shell scraping out whatever he could reach. I don't know if he killed it or it was dead when he got to it... but I saw what I saw. They are very opportunistic feeders, that is for sure.
 
all i'll say is that i never caught as many catfish using chicken livers as i did using shrimp... o.o
 
I like to smoosh any pond snails that I see on the glass, my ghost shrimp won't do anything to the live ones, but they love the recently deceased! One will usually grab it right after it hits the bottom and pull the whole thing over to a hideout to feast.

It's a fun way to control the pest population =)
 
I have Ghost Shrimp in my 55g with Angelfish, the angels have no interest in them, and the shrimp got big, and turned a brown color.

Here's a pic of one of these mofos.

They were cracking me up tonight. I threw in some sinking shrimp pellets for the cories and the ghosties went nuts and started stealing them and hiding in the anacharis with their loot.

Unfortunately I took some completely worthless pictures of this activity. :(

It's difficult to tell the size of you shrimp. I am fairly sure it's a female. However, it may be a P. paludosus, or possibly M. lanchesteri. Given the apparent size, I am leaning towards a common Ghost (P. paludosus) species.

it's possible, I have read cases of aggressive ghost shrimp. Gotta be something in the water :lipssealedsmilie:

Palaemonetes paludosus are actually not that aggressive. Their main feeding tactic is to grap a piece of food, then swim/hover in the water away from anyone else while they devouer it. They are not hunters, rather opportunistic scavengers.

There are cases of shrimp sold under the wrong common name. The vast majority of ghost shrimp sold in pet stores are wild caught. Hence, any number of species can be snagged along with Palaemonetes paludosus (common Ghost/Glass shrimp).

Palaemonetes paludosus are easily distinguished from all Neocaridina or Caridina sp by the length of their rostrum and chlea (nose and claw/leggs). However, it is extremely difficult, actually impossible for most, to distinguish juvenile Macrobrachium species form Palaemonetes species. Macrobrachium shrimp are more aggressive than Neocaridina and Caridina species.

While most are not 'blood thristy' they do go after food with the enthusiasm of a 15 year old boy after a fresh pizza. The truely aggressive Macrobrachium shrimp are the adult 'alpha' males. Larger species are know for extreme acts of violence. They can, and will, devouer any living thing in their tank.

I would say the one pictured is about 2", one of the largest. From the reading I've done I would agree that they are P. paludosus.
 
Well, either the shrimp are really good at hiding or bad at hiding. I only counted four last night.
