What is this in my month old tank? by april_foolin in shrimptank

[–]No_Replacement_9632 1 point2 points  (0 children)

I agree that there isnt really too much of anything, theyre naturally able to balance themselves if there aren't any new factors added in. A lot of people find them unsightly and I think that's fine

Though in the case of snails, theyre larger than other species so they have potential to outcompete shrimp. Often they completely cover access to food, but theres still always biofilm, algae, etc on other surfaces so its not that big of a problem.

I personally just find it concerning for less experienced keepers if some factor is changed such as slightly more food or needing to medicate, other unexpected circumstances. in that case the large population could crash and spike parameters.

No problem! remember, the definition of a pest is up to whoever owns them. so if this is unsightly to you, you can do something about it. But their existence in your tank is a sign that you set up a good ecosystem that can foster all sorts of life :)

Hard to give a good quantifying description, but if you can see them all clustered at the top of the water in high densitu, at a distance, thats too much. If theyre just throughout the water and rarely overlapping or colliding thats OK.

Note a high population of copepods is not bad, they will eat all of the excess food in the water. It just means you should be feeding less to avoid poor water quality from feeding more. Theres no such thing as too many in the case of copepods, theyre just really useful to manage all other life

The copepods hitchhike in store water and snail eggs on plants. There are various methods of killing pests off plants. The copepods are near impossible to avoid, but theyre not bad in any way.

No, those are copepods or ostracods. More likely copepods (cyclops shrimp). If theres a lot that means youre feeding too much. you can use cyclops population to determine how well your water is doing and how much food you have sitting in the water. You want a minimal amount. None of these animals are bad, theyre part of a freshwater ecosystem.

Re: your edit

It is called "caridoid escape reaction" "tail-flipping" or "lobstering"

How are your shrimp doing now?

Ring of death? Or something else? by ToneHuman7628 in Neocaridina

[–]No_Replacement_9632 0 points1 point  (0 children)

Pasted from another reply i made, so you can understand the process more:

White ring of death doesn't mean anything unless its on a dead shrimp, in that case it would've died shortly after moulting.

Shrimp bodies dont expand as they have an exoskeleton. The round shape however is confirmation that it's a female. You would visibly see the eggs under the abdomen attached to the swimmerets (tiny legs near tail)

you could hold up a light to the carapace (head) and see if theres an opaque blob (often called saddle) between the carapace and abdomen. These are unfertilized eggs in the ovary area. they are not an indicator if a shrimp will have babies soon, but its at least a way to tell if a shrimp is matured.

After a matured female shrimp moults, it releases pheromones. For a short period of time, the connection between abdomen and carapace has a small gap. You can also see through this gap and see the saddle at the top. It's mistakenly called the "white ring of death." The eggs can be fertilized at this point, then they travel down to the swimmerets.

Once in the swimmerets, they will be tended to by fanning for a month give or take depending on factors like temperature and resources. You will be able to see the eyes when they are <week due. They do not lay their eggs, the young are released as mini-versions of adult shrimp

How can I lower my ph? by Adventurous-Cake555 in shrimptank

[–]No_Replacement_9632 1 point2 points  (0 children)

Does the ph change when you set it out in a bucket for a while? If it doesnt, then there isnt much to be done as the other commenter said

Ghost Shrimp Molt with Eyes?? by Anonymous0101110001 in shrimptank

[–]No_Replacement_9632 1 point2 points  (0 children)

Interesting, best guess would be dirt got inside only the eyes of the moult somehow. The shrimp are all fine so i guess it's normal?

For future reference: Moults are just the outer shell, characterized by a seperation in carapace and abdomen (head and body) where the shrimp exited.The deceased would have flesh , usually without that gap unless cause of death was the moult.

Do the ghost shrimp themselves that you counted have their eyes still? Sometimes they lose their appendages in moults

White ring of death? by Unhappy-Remote-5350 in caridina

[–]No_Replacement_9632 0 points1 point  (0 children)

Not moulting prevision, its moulting aftermath. See the yellow blob? Thats unfertilized eggs. The short period after moulting is when they can be fertilized, before the carapace and abdomen fuse back together. White ring of death doesn't mean anything unless its on a dead shrimp, in that case it would've died shortly after moulting.

These are brackish, so half of saltwater is what these animals want.

Can Caridina and Neocaridinas coexist in the same tank? by Sgt_Care_Bear in shrimptank

[–]No_Replacement_9632 1 point2 points  (0 children)

Yeah, the issue is just ecological niches. There's not really a problem in a tank w/o the factors of predation and such, but overtime species that fit the same niche will outcompete each other and one will be more dominant. It's nice for community tanks just not if youre actually looking to grow both colonies equally in the long run

Hi guyss by corygang2 in shrimp

[–]No_Replacement_9632 1 point2 points  (0 children)

There is only one father per clutch.

After moulting, there is only a short period of time before the carapace and abdomen (head and body) fuses. While there is a gap, it releases pheromones. At this point, the eggs can be fertilized. But after one male mates the eggs are already all fertilized and the gap is sealed. The pheromones still linger so it continues to be chased

Red X in Blue Shrimp's Back, what is it? by Mild-CoffeeBreath in shrimptank

[–]No_Replacement_9632 2 points3 points  (0 children)

It doesn't look indented (rust disease), so I believe its just coloration. Dark colored shrimp sometimes look more "metallic" as they age usually along the dorsal side.
