RCS random death woes

Hi guys,

I've an aquarium set up a year or more ago. It crashed about six months ago from neglect when I changed jobs... I think someone put in some chlorinated tap water to fill it back up.

It's set up with eco-complete, compressed CO2,dwarf hair grass, hygra, java moss, dwarf sword grass etc.

Randomly my ottos died, flying foxes, Red cherry shrimp, etc. Guppies stopped breeding, shrimp stopped berrying.

Plants flourish like crazy. Nipped plants oxygenate like crazy, but there's not much for pearling like before.

Water tests perfect for nitrite, ammonia and nitrate.

Algae has been a FIGHT. Hair algae and staghorn now.
Water fleas are doing great on the riccia.

Had a massive snail explosing with no food for them... they eat the dead shrimp.

Shrimp randomly die in the numbers lately. If it keeps up, I'm afraid I wont have any left!

Food is Nutrafin Max, Spirulina wafers.

I've tried to find out if it's the food, but when I stop feeding, they die too. They seem to go weeks without food fine, but some still randomly die...

right now like 2+- per day... so I'm stuck as to what it is.

I've had my red cherry shrimp since the beginning on June, and not one shrimp has been berried yet. There are only 13 left out of the original 18 I had. I got them as babies. I also have eco-complete, dwarf hairgrass, a couple pathetic strands of java moss, and some micro sword grass. How big is your tank? Maybe there's not enough oxygen? What is the pH?

Vladdy, what's your tank's temperature? Cherries won't mate if it's mid-sixties or less...

Jedidiah, try cutting back on the CO2. May be too much for them.

my CO2 was perfect green. Lately I turned it back down to like bluish green by the CO2 monitor solution...

I found the plants grew a lil better with less co2.

I am wondering also if it's the snails?
I watched them attack a weak shrimp. (live)

I'm still losing them in numbers, I've noticed that they seem to get lethargic and sometimes lay on their backs or sides and kick their feet randomly.

By the next day, they're usually dead.

I have to test the KH, the LFS doesn't do it here... nor ph lol

KH and PH are not likely the problem

What do you think the issue is? I've pulled everything including the driftwood out that I thought might be damaging.

I lowered the CO2 more, and the plants oxygenated even more. Wierd.

My tank temperature is around 77 degrees F

I have a 15g shrimp tank that was established almost a year ago. I started with 30 and they were doing well until I had a snail outbreak. That led to an ammonia spike in my case and I lost a bunch.

To get things going again, I did some deep gravel vacs and cut back a bit on feeding. Once the snails subsided the colony slowly grew back. I think it takes 2-3 months before the babies seven mature enough to determine the sex, longer for them to start to reproduce. It took a good 4-5 months before the population was noticeably larger and it has been growing exponentially since.

On another forum this week I mentioned how I finally started feeding them to my cichlids again since that 15g tank is crawling with 100s of them. I've introduced at least 30 to my 29g tank with Apistos. Some will make it there, some won't.

lucky

don`t give up! Breeding these guys is weird - some people have the easiest time of it, others like me have no luck. 8 months of trying to get these guys to breed, 0 success. I eventually cheated and bought 6 more, one already berried. The eggs just disapeared one day, poof. Lost another 2 the last month. My parameters are all good but obviously something`s still not quite right.

if you figure it out let us know!

Look at the food ingredients, see if there is copper (inverts killer) in there.
don't leave the dead shrimp or fish in the tank if its small one, and do water change.

Jedidiah - Welcome to the planted tank! How often do you feed your fish and how often do you change water in your tank. I don't think it is the co2 by what you are describing in the first post. It sounds like you are having a mini cycle of sorts.

Without Algae, death of mankind would be inevitable.

it's probably the fertilizers because in my planted i could never keep them but when I got a shrimp only tank they seemed to flourish and explode. Another reason I heard might be the sap from some plants (anubias) are toxic to them so trimming a planted tank could affect them

Have you ever used copper containing meds in the tank?

I had the same problem when I tried RCS - they just died for no reason - typically after a feeding. Like, I would feed, they would eat, and 2 minutes later they would die. Nothing was wrong with the foods I fed and it didn't seem to matter what I fed them Was very sad and I never did figure it out.

I've kept Anubias in my tanks and always had shrimp in them. The concern is the Oxalic Acid that can be released when the plants are cut or trimmed. I haven't seen deaths after cutting in the tank personally and many other have done the same as well. I have a local friend that has a softball sized anubias petite in her shrimp tank and trims it all the time with no issues.
