Hi there. I currently own an 80l tank. Thanks to people help in here I have managed to fully cycle and start stocking fish. Fish have been gradually added over time, minimum of 1 week apart. My stocking levels are currently at the following:
4 x black fin corys
2 x Kribinsis m&f
10 x Cardinal tetras
Iím just wondering how much more I can safely put in. Visually there never appears a lot of fish in the tank, but I know that not how it works.
I'm guessing your tank is roughly the equivalent of a 20 gallon high? If so I'd say you are pretty much maxed out IMO. Just try to turn your tank over 10x an hour or more with filtration and do 35-40% water change once a week. Nice tank!!
Thanks. Itís getting there Iím sort of happy with how it looks. I do a large water change weekly and that seems to keep my parameters in check. I just feel thereís a lot of empty space at the top that fish donít use. The cardinals donít move much from where they are positioned in the picture.
Yeah cardinals won't "fill in the top". They are more of a mid water fish. You could try want King Fisher suggested and get taller plants, or you can also try floating plants and their root structures would fill up that space.
80 liters comes out to about 21 gals. But looking at the tank, the dimensions look more like a 20 high than a 20 long. So I'd stay you're fully stocked. If it was longer and not as tall, I'd say throw in some more cories.
There aren't many fish that are true top dwellers. If you want to fill in the top, tall plants are probably the best bet.
Cardinals and other similarly sized tetras tend to stay towards the middle/bottom of the tank in my experience.
