Hello, I'm still new here
So I keep some RCS in 7 gal tank (30x30x30cm). I use aquabides for water and I put some bacteria starter. The filter is hang-on filter with surface skimmer and the lamp is 5W LED. I use soil and put some plants there (cuba and monte carlo for the soil, and some java flaming moss, some cabomba, and a tonina fluviatis). I keep around 20 RCS there. At first they looks happy. Swimming around here and there but after some time it looks like they are just sitting on one spot not tends to not move. Some of them are molting and usually the "ghost" will be eaten by others but no RCS touched that skin. I put some HIKARI Shrimp Cuisine and they don't even touch it. Today when I checked on them nearly all of them are dead at the bottom of the tank or outside the tank. All is dead except one RCS that hang on the carbon filter (outside the water). I put the survivor on a glass with distilled water and some tissue. I observe it and it looks like the RCS is covered by some diatom by its mouth and when I transferred it into the glass it looks like puking diatoms too. The water on the "graveyard" tank is somewhat slimy and the surface skimmer can't absorb the slime. What must I do and what is wrong with this tank?
My RCS seem to have halted breeding over the last couple of months. I am not sure if this is heat related or I am just not getting them in the mood. All parameters are fine, with a TDS of around 150 (I am keeping them with CRS). I am thinking of doing a 20-30% water change on the weekend to see how that goes.
Anyone have any thoughts on how to set the scene?
As a side note I was in HK last week and wow it is so impressive walking around and looking at all the brilliant shrimp places, the colour and quality of the shrimp is nothing I have seen. Very impressed.
Im wanting to set up my first shrimp specific tanks and need some advise and recommendations
I only want to keep cherry shrimp but a fair few different colour varieties so want either a large divided tank or multiple nano tanks and ideally id like to run sponge filters all off one air pump
So here are my questions:
1. Is individual nano tanks or large divided tank better?
2. If large divided- is glass or mesh better for actual dividers?
3. Whats the best options for heating for both nano and circulation of heat in a divided tank?
4. Do i need shrimp specific substrate for cherry shrimp? My tap PH is 7.8 and RCS seem fine with that in my community tank
5. Will separate sponge filters for each divided section/tank be enough filtration and oxygen or will i need something better?
6. What sort of air pump capacity will i need if im using gang valves to split? Do i go by total litres of all volume or even more than that?
7. Whats the smallest tank size i can go for a small colony- not looking to mass bread and dont have much space.
8. What are the better plants (specifically moss & small ferns etc) for low light?
Id really appreciate some advice and specific product ideas if you have anything you recommend because i want to do this right and im going to take the time for due diligence- ive attached photos of some ideas i like so far
I bought 7 RCS for my 2.5 gal tank yesterday (no filter/heater). I also have a marimo ball as well as some java moss. I was wondering if this no filter set up is okay for my RCS? This morning they were acting less active than yesterday. They weren't picking at the marimo ball or anything, and were all just standing still..
Over the last couple of days I have head some RCS deaths. One I am not sure why and the other one I felt like she was going to die as she could not moult (I could see her shell almost split in 2 at the saddle). All females in this tank are breeding exceptionally well and all other shrimp seem fine.
My water parameters are:-
6.6ph 0 ammonia 0 nitrites 10 nitrates 200 TDS (a bit high for my liking prefer around 170, so will bring this down slowly) I keep these RCS with my CRS shrimp. So I am just wondering if it is my setup that is causing these issues or just coincidence that these two deaths happened at the same time?
