Just wanted to jump in here:
the kind of trigger you pick makes a big difference on the chances of success.
For example; if you put an Undulated and a Titan in the same tank= World War III
But if you try a Sargassum (Red Tail) and a Blue Jaw= better chance of success.
There are some real well-known nasties that don't play nice for very long. Like Clown Triggers, Titans, Undulated, Pink Tails, Fuscus (Blue Line), Queen Triggers, and IMHO
Picasso's. Lots of exceptions to this, I am sure, but in general....
