substrateless tank ok?

The aquarium silicone and gravel is placed on the inside of the tank with the gravel covering and sticking to the silicone. This is a proven method used by many and disclosed in books, articles, and the like. I will locate one and post it later.
 
Doing the inside gives you a lot of options. You can start by placing larger rocks then work your way down sprinking the finest gravel last. This way you can have a great looking tank that is great for bottom feeders and easy to siphon. This method also works well for taking on digging cichlids. Some larger cichlids however may eventually rip out some rocks and gravel.
 
i thought the idea here was a substrateless tank for plecos. so where did the silicon and tile ideas come from? bear in mind that the tank below needs to get light...
 
If you reread the responses, he doesnt want to light the fry tank beneath.
 
No the big concern is uneaten food.Those live worms crawl down and you never see them again.Also the ability to shiphon off the waste in like 30 seconds so I can do It daily.I have a piece of slate that fits if I trim it a bit for the bottom.
DIY tip to cut soft rock turn a plywood blade backwards in a circular saw go slow and this is the one time you realy have to wear those safety gogs.Personally I use my concrete sideing blade:D
 
At my work we keep 200 bare tanks and about the same with UGF setups the bare tanks have less losses than the graveled ones.I just know the plecos love the live black worms and will munch for hours if they can get them in a pile in the corner.I have the royal and now three albino brissle nose I would like to breed someday.Now the albinos are 3-4" anyone know what size they will breed at?
