Well, I made it. There are a few unexpected twists and turns along the way. I was terribly sorry to read about The Oil Spill of Summer 2019. I was touched by the father-daughter anecdote.
After 3370 posts, though, I can confirm inception of rainbow tank ideas...
But a lot needs to happen before I can go this route. Like, I need new floors first. And I need to finish my master bathroom remodel... Lots.
For now I will stick with my 10g + 20L + 36BF. Hopefully I can get there before my largest clown loach outgrows the 36.
