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!

bah wrong section, ignore this.

Even if it is the wrong section, I will still reply. If you are looking for some type of algae eater, then a 'hong kong pleco aka hill stream loach' as they are suitable for cold water, I don't recommend you get fish that swim in schools in a coldwater environment, they are mainly only tropical fish that swim in schools.

Hi,

A fish which might work is the white cloud mountain minnow. They stay small and should be in groups of 6+. They may be at rish of being eaten once the goldies get a decent size. They are available in couple of different colour morphs and i think there is a long finned variety too.

Hi,

Surface area against volume is very low compared to a 'conventional' tank, if there is such a thing. I would recommend only stocking to maybe 50% of the level for a more conventional tank. Maybe two more fish, at the size you already have, introduced slowly, and keep an eye on tank parameters. Take it easy, and you won't hurt any of the present occupants.
