You need a tank, food, water purifier, someway to aerate the tank, and (of course) sea-monkey eggs.
Terrapins are types of turtles that are found in brackish water. If your terrapin is not eating, there could be several reasons why. The tank could be too small, the temperature can be too warm or cold, or they could be sick.
terrapins, like most other turtles need: a basking spot plants so they can 'hide' a UVB light over the basking spot don't use gravel because that might lead to choking a water filter
yes otherwise they will eat eachother
Yes they do but they also need a small bowl of water for them to bath or swim in. If you are thinking about keeping them as pets, you should get a warm light and put it in their tank with a rather large area or water to swim in also.
Depends on the fish. You need to be more specific.
The answer is yes. Fish do need at least one male in the tank to fertilies the eggs. However in some cases the fish will first lay the eggs then the male will fertilize them.
Goldfish just need a plain bowl and some plants
Well, first, your eggs should be in a separate tank from all the other fish, ok? Then, when you clean the tank with the goldfish eggs, I usually never clean out the water completely. I usually just dump out 25% of the water and replace it with clean water. I'm sure no harm to the goldfish eggs will be done if you do partial water changes, and partial water changes are all you ever will need. However, if you REALLY need to clean out the tank completely, usually goldfish lay their eggs on aquatic plants or objects. If you move the plant or the object to another little tank or a safe place while you clean out the tank, I'm sure there will be no problem. When your done, just replace the plant/object into the finished tank.
the water won't affect the eggs and they still have plenty of time to hatch
