I would suggest either a Neon Goby, Yellowline Goby or Sharknose Goby (Elactinus spp.), Court Jester Goby (Koumansetta rainfordi) also make wonderful additions, A Small Basslet of the genus Liopropoma spp. or a Royal Gramma also should work well with your existing tankmates, and lastly another great group of fishes include Shrimp Goby of the genus Stonogobiops or Amblyeleotris. For shrimp goby, one bonded pair with their commensal snapping shrimp of the genus Alpheus makes a fascinating addition to smaller marine reef aquaria.

Thanks for reaching out about you fish. It is believed to be a Comet goldfish. Water quality and nutrition is the key to success. Testing water parameter for pH, ammonia, nitrite and nitrate will give you guidance for a healthy environment. Purchased food should be rotated out every 3 months as vitamin C and other nutrients degrade over time. Trying to maintain water temperature can be challenging with out a heater, but most fresh water fish tolerate some changes. Good luck.

Mollies do come in gold or orange colorations, but it is difficult to determine from that angle. If you can repost a broadside picture in a new question, that may make identification easier. If it is an egg laying species of fish, the third image could be an egg but I have reservations saying definitively without something for scale. It looks too large to be an egg. As an aside, if you leave the Molly fry in with adults, they will likely be eaten. You can separate the out, remove the adults, use a breeder screen or provide plenty of cover for them.

Food, genetics and stress can all affect colors. There are color enhancing diets that you can buy. Maintaining pristine water quality and stable chemistry will limit stress. If the fish has muted colors due to genetics, there is nothing to be done. As far as being "shy", this can be due to anything that is stressful or potential illness or injury. This would require and exam to diagnose.
