I can't say much for A's and fish tanks, but my brother-in-law and my brother both have a thing for fish and they both put in lots of money and time into them. My brother is WAY more obsessive about it (to the point I wonder about it and him having some addictive personality--he spends money he doesn't have on it). In both cases it is an expensive habit and IMHO your AH shouldn't be spending money of fish when you are struggling to survive. Seems pretty selfish. Maybe the fish stuff should be sold the next time your family needs food---there are plenty of collectors out there that might be interested.
