Ohh I love this idea! Goldfish are some of my favorite fish to keep. I should get some new pictures of my guys. Anyone else who has pictures should post them, too!
Here are some other facts that are commonly missed by LFS employees:
2. Goldfish need a variety in their diet.
While the pellets we get at the store may seem like enough; they can often cause problems for our golden fishies. Goldfish are omnivorous and need both plants and protein in their diets. Young goldfish need diets with around 57% protein, and older goldies need diets with 43% protein. All goldies need greens. Spinach and red lettuce are two very good greens to offer. Place them in a lettuce clip and watch your goldfish go to town on them. Slices of orange can also be placed in the lettuce clip to add more variety and vitamin C to a goldfish diet.
3. Goldfish can live with plants!
Most people will tell you goldfish eat all plants. This isn't true. When offered enough greens in their diet, goldfish often mostly ignore other plants. Mind you, some goldfish will still nibble on your plants, so never try expensive, delicate plants with goldfish. Some good plants to try are hornwort, anarcharis, duckweed, water sprite (although my guys love to nibble on it), anubias, java fern, and moss balls. Your goldies may eat some and not others. The key is to find what works for you and your goldfish.
