Hi Randy! I'm going to try and take a crack at these questions, and if anybody disagrees, feel free to chime in:

1. Clown gobys like to perch on corals...they *prefer* branching type corals, and will actually lay their eggs on the corals. This type of goby is best kept with other docile species, but one advantage this type of goby has is that it has a type of body slime that is noxious and keeps *most* (but not all) predatory fishes from eating them. I'm sure this goby is probably irratating your soft corals...long term effects? I guess it depends on the coral. I would definitely keep a close eye on the appearance/health of your corals. Although this type of goby is known to occasionally nip small coral polyps, it is not supposed to create any irreparable damage.

2. Crabs and shrimps molt as they grow. Do not remove the exoskeleton, as it is high in protein and nutritious for either the molting creature or other creatures in your tank.

3. Uncured LR does not need light while curing, but since it usually takes about two to four weeks for all traces of decay and odor to disappear, it is *definitely* recommended to do several complete water changes during the curing period to purge the system of toxic nitrogenous wastes.

4. Hmmm. I'd say high hopes are OK for some, but not for all. I really need to know what types of predators you are planning on keeping, which tank (size) you are planning on placing these creatures, and exactly which types of invertebrates you plan on placing in there with the predators.
