Something about your volume is mistaken, if it's 2.5 meters long and 1 meter wide and 1 meter tall it would come out to
1,750 Liters or roughly 463Gal. Determining this is the first step.

I am not experienced with all of these fish, but space alone is not your only consideration, some of these are social fish and prefer groups of their own kind (silver dollars, possibly geophagus) and won't do well long term as a single of their kind.

Others such as the eel, knifefish, elephant nose, and archer fish may have specialized feeding needs and struggle to compete in such a mixed tank.

Hello; 300 liters is around 75 gallons. Offhand I would say you are overstocked. I sense you already know this based on the post. More specifically I say it depends. Some of the "depends" have to do with how often and how much you do water changes (WC). Another aspect is do you have live plants either in the tank or external.

While some fish keepers want to think massive amounts of power filtration can take care of overstocked tanks, I tend to disagree. Lots of HOB's or sumps help in some respects. Better to have the extra power filtration than not but not really a panacea.

So, more information is needed. How much and how often do you change the water? Do you have plenty of filtration? Do you feed everyday? Is the food consumed within ten minutes?

Hello; Good catch. That is near eight feet long & three feet wide & three feet tall. Changes things a great deal.

It is quite simple, 2.5 X 1 X 1 = 2.5 cubic metres, which is 2,500 litres.

Haha, you are correct. See I'm a dumb American and don't think in metric(though that is a pretty simple one) so I punched it into the tank calculator, which defaulted to 70% full for some reason.
