Weird chasing sucking behaviour from oranda and ranchu

Hi guys

Work up this morning to some weird behavior from my 2 fish.

They are taking turns in chasing and sucking each others body like they have found some delicious food on each other. It's quite frenzied, they always get along so well it's a little distressing perhaps something external must be causing this.

I brought an aquatic plant a few days ago (anubias) and I didn't bleach or quarantine it, the guy in the aquarium shop thought I was crazy for suggesting it he told me the worst thing that could happen is that that tank would get snails (and this is a specialist aquarium shop) :no:

Now I'm worried I've introduced some nasty parasite into the tank

I will keep an eye on them today and take a video if this behaviour continues

Oh sorry I will post parameters in my next post, I did a 50% WC only a couple of days ago and all parameters were fine!

Any suggestions?

Hmmm so there seems to be an ammonia spike will do a WC however still doesn't explain the aggressive behaviour, video to come shortly

Fantailfan - yes in retrospect I did notice a single white creamy fish (not of the goldfish variety) in the planted tank

Hey guys, thanks for all your responses!

I am happy to report that my fish are best of friends again :happydance

I have been reading a bit lot about territorial behaviour in fish and believe the aggressive nature of my larger fish (in particular) was a territorial claim of the new plant added to the aquarium

It really has beautified the tank, they are more lively, use a lot more of the tank (instead of their usual preferred corner)

Every morning I chant to my girls "plant is your friend - plant is your friend" so fingers crossed they don't destroy it.

Eventually I really want a tank full of plants

Cheers x

I introduced a plant into my tank and had eggs the next morning. Sounds like spawning behavior maybe. Was the one fish bumping to other near its "stomach"? Look for eggs.
