Multi agression - not sure what to do

Postby snare3485 » Sat Mar 04, 2017 4:37 am

Hi,

I have 4 unsexed multis in a 40 litre tank. I've had them for about 3 months now with no hiccups until yesterday when i noticed one of them was getting overly picked on. He was cornered and fins were damaged. I thought it may have just been a territorial thing, so I moved all the shells and rocks around and gave them a bit more food than usual to no eval. Its still being cornered and Im not sure what to do now. I cant upgrade the tank size as I have no room so if thats my only option I may have to remove one which will suck. I've attached a photo in hopes to get some advice on how I should rearrange the tank perhaps. I've seen no signs of breeding so I'm only assuming its territorial.

PS. Ammonia and Nitrite are 0. I do 20% water changes each week. I feed them roughly a pinch of Hikarai seaweed extreme (small) once or twice a day.

Top left corner above the filter is the fish in question.

Thanks in advance.

You could try a few things and hope it improves but no guarantee.

Add a lot more shells and maybe reduce the amount of sand in the tank so there aren't as many unburied shells. I find that an inch of sand or less is helpful!

Use the rocks to split the tank in half to define 2 territories.

Add some floating or tall plants (plastic if you need to) to have somewhere for the bullied fish to escape to.

What are the dimensions of the tank?

So not long after making this post, I found 2 fry emerge from a shell in the back. So turns out they are breeding :). As for the bullied fish, i've arranged the rocks to define an area for the litte guy. 12 hours since the change i've noticed they bother him very little now. All is well.

The tank is 60x30x30cm

I want to support what Dee said...when I think multifasciatus I think in terms of 100 shells/colony and some of them in two layers (piled up).

Once they start breeding, they don't stop. And before you know it 4 multis in the tank will turn in to 20.

I actually got brevis for my 72" tank because I did not want as many shells as multifasciatus like.
