If the eggs in the net turned white the same time the eggs on the tube did, chances are they were not fertilized so the lack of the bubbler was not the main cause.
You can use the 5 gal
bin for the next spawn but get yourself a heater that can handle keeping the water at 78-82 degrees F as that's what is needed to hatch the eggs without post hatching complications. All you will need for that is an air stone and the heater and clean water ( not the water they were laid in.) It's all described in the "wigglers at last!!!" thread.
As for how to stop them from spawning on the intake tube, you have to take that option away from them. Place a piece of slate in front of the tube so that the fish spawn on that instead of the tube. That will help make things easier for removing the spawn. As for removing the eggs alone, chances are greater you will burst the eggs before you remove them so it's not a good idea. Better to make them spawn on something removable. Keep in mind, using a HOB
filter in a breeding tank ( whether the intake is hidden or not) moves the water too much and you risk poor fertilization. I would still replace the HOB
with an air driven sponge filter and that will definitely stop them. ( I have had fish use the lift tube of the sponge filter to spawn on when there was no slate available so you need to get some place better for them to spawn on.)
As for making the fish use something else, in my case with this new pair, I was cleaning tanks when I saw the female cleaning the silicone in the tank corner so I put in a slate she had used before on to the side glass adjacent to where she was cleaning. She went over to the slate and started cleaning it but then went back over to the corner again and continued cleaning. I then moved the slate over to the corner, blocking her access to the silicone, and they spawned on the slate. What the difference was in regards to where the slate was is anyone's guess but that's how you force the fish to choose another spot.
