Swordfish and Blue Marlin are engines based on Stockfish and ideas used in Bluefish by Eelco de Groot. The main purpose of these engines is to provide interesting and effective chess games. Recent versions are quite strong and can be useful for analyzing sharp positions where regular Stockfish can overlook some tactics.
Swordfish has a reasonable balance between strength and tactical abilities. It still has solid style of playing and achieves good results in test suites.
Blue Marlin is more focused on king attack and sacrifices. It is a bit weaker than Swordfish, but provides very sharp and attractive games.

Swordfish 14.7, Blue Marlin 14.7
Re: Swordfish 14.7, Blue Marlin 14.7
Note that old net in Blue Marlin 14.7 is used intentionally to make it as tactical as possible. In my testing it solves the most positions with extremely low average solving time. These nets have also been tested, none was better:
