Re: Pseudomugil furcatus and Marosatherina ladigesi aggressi
Hi Francesco,
I am presently breeding two Pseudomugil species, namely; P. gertrudae and P. signifer. Used to keep P. furcatus and the Celebes rainbow (Marosatherina ladigesi) and from personal experience, they can really bicker amongst themselves and closely related (or similar looking) tankmates like the P. signifier.
However, it is during such times that one can observe males sparring and displaying their finnage but in a community tank with more peaceful and slower growing fishes, like the Clown killie, their almost-non-stop harassment can cause alot of stress.
Like Zebra fish (or danios species), there seems little we can do to curb their hyper-speed activities except provide ample tank space and more turbulent water movement. They will bicker less when well fed and contented but the only time they don't "fight" is when I switch off the lights!
Oh... and don't believe everything you read. The "peaceful" label is very subjective, as in, "I might not kill you but I'll probably harass you to death"
I'm back & keeping 'em fingers wet,
Ronnie Lee
