you're doing this for a hobby or for a living? jk
You sound like you need to either buy or built the stand you'd find at the LFS that hold MULTIPLE tanks for you, like uhm "fish wall" to house all your tanks
I thought when I had 7 scattered around the house that that was quite some but 15....that's a lot. Thou I do like the idea I seen on your Aquariums page with the multiple shrimp set ups, love that, I'll only have 2x10g dedicated to shrimp (unless Santa brings me some more tanks lol)
Oh I LOVE your Boseman's Rainbows, I miss my guys, I still think they're wonderful fish - Are they part of the showtank gang??? I hope so
Love the way your "Bar Tank" is planted, thumbs up on this one!
Dang I wished you were close to me, I'd loveee to come sit & watch all these tanks (and bring along the doggie for playtime lol) I really miss not having 'fish people' around me no longer since we moved.
