I like the new look, that size tank would be a good grow out tank for young Acarichthys, but in the end, it'd be a bit cramped, might last 2 years in there. Mine killed each other in a 150 gal as 3 year old adults (although maybe albinos have that natural instinct need for space washed out?) . That 220 you had when you lived on the WI/IL border would be the perfect tank for Acarichthys.
I sold the 220 to Sawboy before I left. Of course, Wife said, "I wish you kept that one"! I am going today to pick up a 10 pack of Redline Moenkhausia Tetras (Moenkhausia Agnesae) to be my upper mid column. (Cichlid are last to add) Based on your experience I thought 1 of the albinos would be good with the guinacara (Read your old post on your experience with them) but listening to
**** if I had the 220 still, I'd buy every heckeli they had!
