Yoyo loach turned mega bully

[Gill Passman]

I was walking past my 6 footer this evening and noticed two of the YoYos going head to head…..one of them was coming off quite badly and I could see missing scales and red marks on his body….the other was nipping him but he was also fighting back…….When I approached the tank they both ran away to opposite ends of the tank – the one fairing worse took his chance to go and hide in some driftwood…..the bullying one went and nudged some Clown Loaches who had no truck with him…..

 

I’m used to the odd stand off with the Clown Loaches – greying out and a bit of shoving – but have never seen them physically harm eachother. Is this sort of behaviour usual with YoYos? Or do I have a rogue bully in the tank? (chances of catching him or the other without tearing down the tank are nil and even with a tear down nigh on impossible)

 

TIA

I have 3 yoyos in my community tank, 2 of which love to spar. Last
night was a particularly bad quarrel so I posted a similar question on
another forum... I was told that it is somewhat common and can be
attributed to dominance. I haven't noticed any damage done in my
fights but they certainly do go at it with vigor. Mine go nearly white
and circle and roll in a fashion that looks like they are going for
the gills (not you, the 'real' gills, although I am sure you are in
fact, real).

Every now and then I think they may be mock spawning, but I have been
told that is likely not the case either.

The odd thing to me is that the 3rd yoyo in the tank is never
involved. This has happened a half dozen times or so in the past few
months and it always appear to be the same two fish. It also seems to
happen shortly after feeding, I want to say after I feed frozen
bloodworms or cyclops but can't be sure that is the trigger...

At any rate, good luck and hope your fish are well. I will post if I
find anything that looks more conclusive than personal experiences.

Most of my experience is with Clowns and Yoyos, but I think all the
botia break into two camps. There are those that are definitely much
more aggressive to each other and other botia (on the top of that list
is the Yoyo, though I think the Redtail, Blue, Tiger, Skunk and Zebra
also have the potential). Then there are those which are much milder
with each other, and ignore other botia (Clowns, Chain, Dwarf etc).
Generally, the smaller botia are less aggressive, and while I consider
Clowns to be mild, this is during the 'infancy' which is when we
normally have them. I think Clowns have the largest potential to
become killers when they're fully grown, but this takes many many
years. Pound for pound (gram for gram), Yoyos are the biggest pain in
the .... and my next vote would go to the Redtail.

They are still at eachother - not sure who is winning at the moment.
The clowns just treat them with contempt when they bash into them
during their ongoing wrestling match.....
