[Can someone help me identify my Cichlid?]

Oh yeah!  He's about 4 - 4 and 1/2 inches.  How big will he get?  Is 75 enough?

[Can someone help me identify my Cichlid?]

Hey Guys!

Can someone help me identify?  He's hard to get a side picture of.  If I could pet him he'd probably like it.  lol    Got it from a friend who is moving and he didn't know.  He or her is REALLY really aggressive to my other fish which I put in another tank.   Thinking other fish might not be a good idea.  Curious if there are some cool shrimp or snails... etc that I might be able to put in the tank.  If not I'll just let him have his own 75 gallon tank as I really enjoy his charisma.  Named him Marshall!
