125 is a planted discus tank. I used to live in Houston as well.
2 Wilds (Fish Ranch 2 in Houston)
2 Leopards (Fish R Us in Houston) - (1 is very slow growing)
2 Gold Melons (Discus Dan in Houston)
1 Blue Diamond (slow growing)
2 Red Turqs (1 slow growing)
2 Scribbled Reds
Tomorrow I get 2 4+ inch Red Melons, 1 3+ inch Blue Diamond
I also have 4 simese algae eaters (4 more tomorrow), 6 L-134 (my favorites), 1 albino bushynose, a school of cardinal tetras, and a betta in there.
I use a sump filter, and change 50% of the water a week. I may have to take it apart and completly sanitize it because I am having a battle with ram horn snails. The snails are eating my plants...(I offset the cost of the aquarium by suppling a LFS with plants, not much, but about $40/month in store credit).
Houston really has some great LFS
