If goldfish are kept in dim light or in a body running water such as a stream they will loose there color. They remain gold when kept in a pond or in a bowl with adequate illumination.
Go to Wal-Mart and get specalized rocks that absorb waste in the water.They will normally be blue and grayish-white. I have a snail in mine to clean away the dirt but just one they breed
I think good fish names are Bubbles, Wiggles, Wonda, Cosmo, Heidi, Jewel, Coral, Goldy, Monty, Sunny, Squirt and Willow
Portuguese man o'war (Physalia physalis) is not a jellyfish, however it produces a liquid mixture made up of three peptides:
* hypnotoxine, a neurotoxic poison, which arrests respiratory, circulatory and nervous systems; * thalaxine and * congestine, two allergens, which produce irritation and kill by anaphylactic shock.
Normally goldfish are peaceful and calm.But incase your goldfish is doing so then its better to separate the new goldfish.
