First post from someone who has learned a lot from everyone's generous advice on the forum.
I'm hoping to get some thoughts on how to continue to build out our tank. It's a 40-gallon breeder with an Aquaclear 50 filter. We've completed our fishless cycle and introduced 8 diamond tetras, an albino bristlenose pleco, and two zebra nerite snails. What to add next?
We will almost certainly add 6+ glofish danios (kid's pick). I'm also thinking that a small school of corys (w/ a sandbox enclosed by large rocks) would be a fun addition to add interest at the bottom of the tank. But I'm bit concerned that 8 diamond tetras, 1 bristlenose pleco, 6+ glofish danios, and 6+ corys be too much (perhaps especially so for beginners). That said, according to aqadvisor, it would be about 53% stocked.
Any advice or thoughts would be much appreciated! I'd also love any advice on which cory species would be best (in terms of size and standing out against a black substrate).
