I am sure they will disappear quickly. Just using the RR as a cheap way to "get my feet wet" in aquariums again and cycle the media. If I am lucky enough to raise some, they will be a cheap treat for the YP. I hope to move on to SFS, BNM, etc once I am happy with the setup.
I went with buying discreet components so far but may pick up a 20 gallon kit later. For the RR you need a 12 to 14 hour photoperiod to induce spawning.
