He's an easy way for me to figure if my Opae's were eating or not the biofilm and the few times I fed a small amount of spirulina powder

Pics showing the poop at the bottom.


Here the opae are at the tops edge eating bilfilm.

@Vorteil How do you handle all those load of poop? leave it as it is or vacuum it once in a while?

I am always wondering myself what the best method would be. In my old tank I just siphoned the substrate once in a while but I would always leave a little for tank balance. When you leave the poop for months or years and stir the whole thing up the water will be nicely hazy

I tend to just leave it in my tanks

@odin a question, if you leave it and it accumulates, doesn't it foul the water? in the case where you have lots of shrimp in a tank and with no filter

Same here. :)

By the way: I always thought that Opa ula make quite a bit of mess in relation to their size. One could call them active poopers

I haven't witnessed any issues and the water stays healthy for me.

I just leave it. I try to not disturb the jars. I open them up one a week for air exchange only. Only one of my tanks had sand for a substrate. All the others usa small lava rocks. If you disturb the sand/gravel you could end up releasing the amonia that's trapped in there. I don't feel it will harm the opae. All my opae were fed freeze dried spirulina only at one point in time. All the tanks water is crystal clear even the tank I fed every few days. Granted the glass may look hazy due to the fact that I don't scrub it down often. The algae just build up over time. I will clean sometime this week and take new pics of the tanks only. Jars will stay the same.

Ok understood. Seems like the majority just leave it as it is.. Yeah they serious poop a lot.
