It really darkens the tank up quite a bit. I had oscars in the tank when my gravel was black, so some of it's already chipping. But I think the contrast between the dark substrate and neons would be great.
ok cool i thought i was the only one something about paying for equipment and not needing right now but maybe down the line just hate to kick yourself for throwing money away
i do for sure i have rubbermaid bins full of the stuff old UGFs parts for filters tubing and a ton of other stuff cant throw it away it comes in handy even the ones that dont work anymore i keep for parts i have rebuilt a couple of powerheads this way
I have a shed full of mainly fish stuff 20+ years of keeping fish and never thowing any thing away makes for alot of stuff plus all the stuff my dad gave me from when he down sized from 6 tanks to one
