Ph6.3
NO3 30ppm
NO2 unknown

is it my NO3 too high? any ways to reduce NO3?

As far as I know Otos wont harm ur shrimp but I could be wrong

shrimp feeds on dead shrimp. mostly, the missing part that you observed is very likely eaten by the shrimp. My oto has never touched any of my dead shrimp. From what I have read from many forummers, oto is shrimp-friendly.

ya oto are quite friendly, i only see shrimps feeding on my dead oto.

i think otto will only eat shrimp if they are already dead.. otherwise they are rather harmless tank partners with shrimps..

I removed my oto and add in ramhorns snail instead as i am afraid oto may accidentally suck the shrimplets as my tank is only 1ft cube which is quite small and they are moving quite fast compare to snails. However if your tank is quite big (2ft and above) it should be fine with otos.

You may contact Ariel as her tank got plenty of ramshorn snail. Think she is selling 5pcs of small snails for S$2.00 but you have to self collect from her at Yishun near the stadium there.

Otocinculus will not ever eat shrimp, they are vegetarians. In fact they prefer algae over plants, which is why they are good for plant tanks. I have put ottos in my killi tanks, and they don't even eat the eggs! I would say the safest fish for keeping with shrimp!

Yes the NO3 is too high! Do some water changes and add more plants to keep it low, less than 10ppm for Nitrate is best for shrimp keeping.
