I rarely see copepods anymore but there are tons of amphipods everywhere in my tank. My Melanurus Wrasse and Springeri Damselfish are fat and happy so that probably explains my copepods...Looked in my tank tonight and saw copepods and amphipods everywhere. All over the rockwork and crawling across the sand! I added them months ago and dosed phyto and never saw any anywhere so I have no clue what spiked their population to clearly viewable levels so fast.
