Octopus Detritus (poop)
I have seen three types of elimination. One is a milky cloud (possibly urine). The other a long, almost transparent string with tiny white lumps and the third something that looks very much like mammal poop in miniature. The red color in the image of the third is a result of the Cyclop-eeze the animal was either eating or from the pods (that ate the Cyclop-eeze) that the octo ate.
Welcome to TONMO!

We usually only recommend 55+ gallons for an octo, but it's possible there may be a dwarf species or two that are suitable for that size... HOWEVER it's not likely you're going to be able to acquire an octo with such species specificity - and even if the seller claims a species, the accuracy is usually much less than 100%. Any chance you can get a bigger tank and cycle it?
