Tong's, 15250 Whittier Blvd, Whittier. Great store since the fire rebuild, average prices. Four 300g coral tanks plus a 90g frag tank.
Strictly Fish, 6903 Carson St, Lakewood. Very good selection, above average prices, some sick livestock in the back tanks, but the main coral tank is nice.
Discount Tropical Fish, 561 W La Habra Blvd, La Habra. Typical LFS, little to no corals, not enough lighting to sustain coral. Couple knowledgable employees.
Happy Fish Pets, 799 W Imperial Hwy, Brea. Exactly what it sounds like. They have some corals though.
Charles Aquatic Image, 15041 Leffingwell Rd, Whittier. Brand new store, not sure if they have SPS & LPS yet.
