How big is pretty big ? And are there any hiding places ?

 

[Rbishop]

and how big are the fish?
and how long has the tank been set up?
and some good water readings from a liquid test kit?

 

[Rejoy]

They are like 4 to 5 inches. I think that they are playing and i dont have a water test kit. One comet fish died today

 

[Rejoy]

ithe tank has been set up for months. One arowana and another fish died. These 3 are my new fish. They are almost 1 week old

What size tank and what is your water change schedule and amount?

 

[Rejoy]

I have put 22.2 US Gallons of water. The tanks capacity is 34.4 US Gallons and there are some hiding places

That's a good weekly water change being more than 50% of the tank capacity, but ~34g is way too small for 3 comet or common goldfish.

FWIW, I've got 4 goldfish in my 55g. One comet and 3 fancies. The comet may need to get re-homed some day, but so far he/she is only ~5" long and I've had the fish for 1.5yrs.
