How Many Fish Can I Keep?

[polerz]

I have a very tall aquarium, its an octagon shape with 27cm sides. I've calculated the surface area to be approximately 395 square inches. The tank is about 1.5m high, so its about 382L in volume. If anyone could confirm that I'd appreciate it haha my math is sketchy.

I currently have one 2-3 inch gold fish, and 4 others I'm unaware the names of.

I've taken photos (as best I can, of the fish I have). If you can identify them, PLEASE do! It would help me tremendously!

First fish shots (I have two of the same kind):

Other fish sort of white (I think it has had ammonia poisoning and survived, its gills are off white colour, sort of look bruised):

If you cannot positively identify them, I will take more shots.

That makes a total of 5 fish, how many more do you reckon? I was thinking of getting some cat fish to help the tank out. But apart from that, I dont know. I'm from melbourne aust, what fish do you suggest ? (preferrably easy to get and not too expensive, as I'm new to the fish keeping world). I wanted some fish which swim in schools, I think that would look cool!

Filtration: 1 Jebo 838 cannister filter (1200 Lph)
1 Fluval 4 internal power filter (bout 60gal ph)

Ammonia: 0
PH: 7
Hardness: bout 200-240 atm

Thanks guys!

All of your fish are goldfish & your tank is already fully stocked - actually it will be overstocked as those fish grow - goldies get to around 10" each.

BTW catfish don't help clean the tank - they may pick up dropped food from the substrate but they add to the bioload just like any other fish.

I second that info.

i didn't have the heart to say they were goldfish.
