HELP PLEASE!

Hi,


I've added 2 cardinals to my 450L tank, they have been in there since Saturday, and this AM I noticed that one was looking a little raged. Now I've watched fish A attacking (the now raggedy) fish B. What should I do? They are all that is in there atm, will this stop once pecking order is established or will Fish A kill B?

You may have 2 males and nor a “pair”...unfortunately distinguishing between the two is difficult..if you look between the anal fin and tail, there are 2 ‘vents’ on a male, and 1 on a female iirc . You may not be able to see though.
I would monitor the fish closely and if the one does end up taking a real pasting then separate them, it May settle down but you need to determine the time to intervene

If it is 2 blokes will they ever get on or am I going to have to rehome one/return it?

Depends on the individual fish but long term probably not I would guess... the fact they are the only fish in the tank is probably exacerbating things...

I’ve removed fish A (Bonny), as they were the easiest to catch, for now and have ordered a breeder box to turn up today to separate them... sigh!

You will want to add heater and air stone to the tub it’s in ...if box doesn’t arrive today you will need to think of filter also..

These things are sent to try us ✌
