hey everyone so i know this is a shrimp forum but im betting that most of the people on here have fish too
im a school student and ive decided to design a new breeder box that beats the flaws of other existing products for my major work
i was hoping you guys could just reply with what method or model of breeder box you use to save your fry, what kind of fish you use it with and any pros and cons of these methods
thanks in advance for any replies.
Curious how much i should let them age if its even a concern before i sell some of my babies.
New to shrimp keeping and trying my best! I think water parameters are OK, have live plants, filter, light on a timer, heater and RO water with weekly water changes and testing. Fed 2x a week 1 ball per shrimp of 'shrimp enhancer ' supplement (calcium and magnesium in etc) but 2 shrimpies have an issue... sort of discoloured/opaque orangey bit on their backs.
Can't find anything similar in pics so hoping for diagnosis and way to fix please!!
ps. Apologies for crap picture, phone won't focus!
I've had 3 cherry shrimp die in the last 2 weeks and can't seem to pin point the issue. For context I had 13 cherry shrimp in a planted 10 gallon with 7 Celestial Pearl Danios. I found the first dead shrimp one afternoon, half eaten by the CPDs. Now about 4-5 months back I had witnessed my CPDs attack and kill a small male cherry shrimp. So my initial thoughts were that the CPDs had done it again, which is odd in itself as they have been fine together for many months. So a week later I found another dead cherry but this time it seemed to have died within the last hour of me spotting it and it hadn't been touched by the CPDs (it was at night, so the CPDs were sleeping). This got me thinking that perhaps, the first Shrimp had died due to something else and then picked off by the CPDs. About 5 days later to today, I found the 3rd dead shrimp again already half eaten by the CPDs, this one was a large adult female. Now on top of all this, I have also had 5 of 6 shrimplets in a hang-on breeder box die. The shrimplets were the first to go and which I think makes sense if it was something to do with the tank environment as they would've been more sensitive. I initially thought I wasn't feeding the shrimplets enough or that it was because I wasn't rinsing the baby brine shrimp I was feeding to the CPD fry. Now that the adults are dying too, i dont think it is a coincidence nor do I think its my CPDs that are the issue.
My speculation is that they are having a molting issues. Now the dead shrimp I found whole had a white line across its back and a cloudy white underbelly, which I took to indicate a molting issue. The shrimplets seem to be having a molting issues too, although the 1 remaining shrimplet molted successfully, and many of the adults did too judging by the many molts scattered about the tank. However, I tested my GH and KH and got 6 and 4 respectively, which I believe is fine from what I've googled. Also I figured if there was an issue with a lack of calcium/minerals could it mean that those that successfully molted could still suffer from a weaker exoskeleton and thus be more vulnerable to the CPDs?
Another possibility I thought was muscular necrosis, as the half eaten shrimp I found today had a cloudy white underbelly too and from memory the others all did (not 100% sure) but I had always thought that was just something that happens when a shrimp dies. I'll attach photos to see what you all think.
I've also considered that perhaps i'm not feeding them enough/well but my previous attempts at feeding them blanched veggies have been unfruitful, they dont swarm the veggies or really touch it (i've tried sweet potato, zucchini, carrots and broccoli). They dont go crazy for the shrimp algae wafers or the hikari shrimp pellets either but I chuck it in the tank once a week just in case but I assume there's enough algae/biofilm for them.
I'm thinking of getting a mineral/calcium supplement for the water but not sure if thats a good idea if my gh/kh is already fine.
CPDs are all fine and healthy.
Anyways here are my parameters:
Ammonia - 0
Nitrite - 0
Nitrate - 0
PH - 8.0
GH - 6
KH - 4
TDS - don't know. I've seen mentions of TDS but not quite sure how important it is with cherry shrimp. Do you think I should get a TDS meter?
Temp - 26C
Water change - 25% once a week with dechlorinated tap water.
Would love to hear some of your thoughts.
Top Left: latest death with white underside (fuzziness?) visible. Top Right: Second death with the white line across the back visible as well as a white potruding underbelly.
Bottom Left: Just a picture of an alive shrimp in the tank, to see if anyone can see anything wrong. Are those brownish discoloration an issue?
Bottom Right: Another live shrimp can also see a white underbelly which I thought was normal?
Hi! I've just started a YouTube channel, and my first video is of my 8 month old no filter Jarrarium. Nothing in-depth, more about the aesthetics...and the cherry shrimp 🙂
Subscribe if you like it, as I'll be posting more videos of other tanks, updates on tanks etc.
Take a look and let me know what you think! Would be good to get some knowledgeable opinions! Thanks🙂
