Those require 250g minimum. Here is a tip that will help you find your perfect fish:
Any time you see one, write it down. Google the fish, you will the locate a vendor that is reputable. Look at their care chart which is usually the first bit of info they give. Check their minimum tank size and see if the fish is too large for your tank. If it says 100g minimum, it cannot be happy in a 75g, in fact I will often look for fish smaller than what my tank can hold to leave room for a few more fish! We all want a fancy dinner plate in our tanks, trust me! I'd love a shark in mine but there is no way a 90 gallon can support that kind of fish.
75 is a big tank, to us humans. It seems that if a fish can swim around that is enough. For freshwater this is slightly more true.
The biggest issue with marine fish is that they are so tiny and live in such a huge and fast body of water that our aquariums barely mimic even the smallest of snails natural habitat. Think about how much room the fish have to swim, at full speed a fish can nearly smack the glass and knock himself out lol.
Is there a particular shape or color scheme you want in a fish??
We could come up with a list of good candidates for sure. There are so many varieties that there going to be something just right for you.
