View Full Version : Video: Weird Behaviour? Are they fighting?

What is this behaviour my Synodontis Lucipinnis (a.k.a. "Dwarf Petricola") are doing here? Are they fighting? I have about 20 of these guys in my 150-gallon. All are approximately two inches total length each. I've lost about 5 in the last week… where at first I thought it may have been due to my "overhaul" of my tank (see http://www.trophs.com/index.php?showtopic=260) I am now wondering if they are killing each other? Any feedback, Synodontis keepers?

Sparring males. My petricolas did the very same thing, especially when one of the females was fertile.

Some observations I have made of my petros. I have my spawning group in a 15g which consists of 17 adult petros and a trio of baenshci peacocks. I have only lost one petro in the year they have been in this tank. I have noticed they hate tap water. They freak out. Bang into the glass. Even if I use dechlorinator. Once I noticed this I started using aged water on all the petro tanks. Adults and fry. With you changing so much water volume they might of gotten some side effect from it. I have never noticed any sparring to the death with these guys.

You have 20 adult fish in a 15 gallon tank?

I have 17 in a 15g. It sounds excessive but it works. I have tried pairs, quads and other variations. The tank setup that I am using now has been working for a year now. I do 30% water changes twice a week on the tank. This tank has probably produced a few thousand eggs. I probably killed the first 1000 or so before I figured out how to raise the fry.

My multipunctatus do it all of the time and i believe that's it 2 males sparring.
