mudskipper?

 

[TwoTankAmin]

Well I will have to pull a Jeopardy move here, the mudskipper, Periophthalmodon schlosseri, is able to excrete ammonia. It can handle more ammonia than many fish.

 
The mudskipper Periophthalmodon schlosseri is an amphibious, obligate air-breathing, teleost fish with the ability to eliminate ammonia actively (Randall et al., 1999).

However, it is not the champ in this respect. Because of this fact I will accept this answer. However, the fish I had in mind is a real champ re ammonia tolerance, it is Opsanus beta, aka gulf toadfish.
 
Go ahead mama, the next Q is yours.

  It is very difficult to participate in this game. Maybe there should be a bonus question for late comers.
