So my next and final fish for my 75gal is going to be a Spotted mandarin goby From all the reading I've done, and people I've talked to, I can tell that they aren't an easy fish to keep, so I'll start off with my questions. 1. Will it get along with my other fish in my 75? (Small yellow tank, 2 clowns, diamond watchmen goby, royal gamma basslet) this WILL be the last and final fish. I don't want more than that in my tank. 2. Does it matter the sex? Does one do better in tanks than the other? Or show less aggression? 3. The diet is one of the hardest things to figure out with these guys, so this is what I'm going to need help with the most. I know that they eat those pods, but over a very long time they can be trained to eat other things like mysis and brine. How exactly do I get a good supply of pods for it to eat? 4. I'm going to be adding a sump to my aquarium by the end of january, It will have one part with live rock, one with a protein skimmer, and I was wondering if there was any type of algae or something that I could also include that can help the mandarins diet. 5. I have about 80-90lbs of live rock already in the tank. I'm planning on adding around 10-20 more pounds just to add some hiding spots for the mandarin, because right now my tank has a lot of open spaces 6. I've read that they ARE reef safe, and I'm pretty sure they are, but I was just going to ask before I put it in my tank with hundreds of dollars of coral. Thanks so much to those of you that have a mandarin, and are willing to help me out! I've been wanting one of these for a long time and I want to give it the best home possible.
