How many eggs does ur average crystal produce?

Hey guys and girls,

after noticing a few of my girls getting really fat i'm curious as to what is an average number of eggs u guys notice particularly in crystals. i know somewhere i've read that 20-25 is normal but just thought to ask to get some clarification on what is the norm.

reason why i ask is because i have or should i say had :( a ss crs girl who was holding 43 eggs. unfortunately i was having troubles with one of my tanks at the time so she didn't make it but she, along with many others were generally that big each pregnancy. i have photos to post as evidence but i must warn those skirmish ppl out there that for the purpose of personal investigation there is a pic with a dissected/decapitated shrimp :( so i wont post them until i get the general all clear.

i am now watching my 3rd gen grow and hitting sexual maturity.. and to my surprise some of them already carry massive loads for their first time. this could be because of an additive i use to promote growth and vitality but just thought to ask first before jumping to conclusions.

keen to hear what my fellow shrimp nuts have seen and experienced so please feel free to have ur say :) or even post up pics of ur fatties ;)

I've never tried counting it on a berried shrimp.

But my last CRS mama dropped 15+ shrimplets. Assuming some eggs didn't make it and some babies might have perished prior to being big enough to count (5-6mm).

yeah i'll agree it's very hard to count them when they are still alive. after she died i tried artificially hatching them (with no luck.. although not too much effort was involved) so that allowed me to do an egg count.. on a second count it might actually be 42 eggs.

I've had anywhere from 5 to 30 shrimplets survive a hatch, although I think there was once or twice when it looked like there was a heap more eggs than shrimplets once they hatched. :encouragement:

Over the years, I'd seen 12-48 eggs...highest survival is 42, and that was artificially hatched (BIG CRS girl, on her last breath)...no idea in a tank environment. Average approx. 20-30, usually in their 2-3 lot.

Their 1st drop probably around 8-15, 2nd+ drop 12-24 ? Really depends on age, diet, WC.... I generally expect between 12-16

      Yeah, cancer risk was a thing I'd seen mentioned a lot when looking into gentian violet briefly. I kinda just figured it might only be as bad as the cancer risk of malachite green as well, but maybe I should look into it more. I've been doing a pretty good job of not getting it on my skin and also avoiding dunking my unprotected hands into the tank water while treating my fish at least, though. Maybe I'll just not use it once I'm done this course of medication anyways, because I know a store I can sometimes get to that's pretty distant carries both malachite green and methylene blue, and in pretty large quantities.

      Can't help you with Gentian Violet, sorry. It is banned in Australia violet for potential toxicity, and even possible cancer risks. I thought it was banned in Canada as well. At least, you now know why there isn't much info on gentian violet medication and it's use. But keep an eye on the snails after a week. If it affects the snails, it might not kill them immediately. So keep checking for up to a week. Much safer options out there. No point risking your own life over unsafe products.

      Hello! I have a tank that currently does not contain shrimp, but does contain neon tetras which I am currently treating for Ich, as well as some bladder snails. Shrimp will be a later addition, likely cherry shrimp but I'm still doing research just to be sure. Initially I'd intended to buy some sort of Ich-fighting product that contains malachite green after doing a decent bit of research on it, most of which indicated that it should be shrimp-safe so I'd be good if I ever needed to use it again once shrimp were actually introduced (though I should note I'm aware shrimp can't get Ich, I'm more wondering in case the tetras could get Ich again, or something else that responds to similar medication). I ended up not being able to find any MG-containing products without either having to travel quite far or wait multiple days for delivery (which I was worried could lead the Ich to be fatal), and ended up picking up 'Top Fin Ick Remedy', a product that contains gentian violet which is a triarylmethane dye like malachite green. The bottle has two slightly differently worded warnings about its use with invertebrates ("not recommended for" and "not safe for" respectively), but when I'd been researching malachite green, I'd also heard of products that contain MG but not any other ingredients that would be harmful to inverts still being branded with warnings that they could be harmful, just as a "just-in-case" since the manufacturer didn't test it on any inverts, and I'm wondering if maybe it could be a similar situation here. I'm having a very very hard time finding information about gentian violet's use in fishkeeping at all though, it seems currently extremely uncommon. What I will say though is that I'm on day 2 of treating my tetras with it, and the bladder snails seem just fine -- in fact today I noticed what looked to be a bladder snail that appeared to be newly hatched (because of its size) that I hadn't seen before that was zipping around the tank without issue. But obviously, shrimp are not snails, and bladder snails are also notoriously hardy little guys, so what I'm seeing right now could easily be totally inapplicable to cherry shrimp. It might even be inapplicable to other species of snails, for all I know. Has anyone else here ever used anything that contains gentian violet in a tank that actually does contain shrimp? Were they okay, or should I make sure to not use it once shrimp are added?

      One interesting thing he mentioned was "Bacteria pressure", which I guess just means number of bacteria around.  Yet I see all these other videos from shrimpkeepers bragging about how much bacteria their filtering system holds. Also interesting is no mention of using anti-biotics to treat bacterial infection.  I think that has fallen out of favor recently.
