Spawning Tank for Egg Scatterers

I am in the process of planning the last rack build for my new fish room, which will be a rack of smaller aquarium specifically for hatching eggs and raising fry.  There will also be tanks used to collect eggs from scattering species.  I used to do this with mops or other spawning media on the bottom of a bare tank, and then net the adults out after they lay the eggs.  The challenge with some species is seeing the eggs, especially is there is a lot of spawning media in the tank.  I prefer to use a false bottom system, with a screen through which the eggs will fall, making is easier to separate the fish from the eggs.  But all the methods I have tried before have never been as easy or as effective as I want them to be.  This time I am going to build spawning tanks with screen bottoms out of 2.5-gallon tanks and set them into larger tanks to collect and hatch the eggs in.  This video will show you how I built that 2.5-gallon egg trap.

  1. When cutting the base off the tank you may find that a squirt of WD40 works wonders in freeing stubborn silicone. Do this once you knife makes the first cut in the silicone.
