We're thinking of buying a 10 uk gallon tank, because he have just the right space for it, but I'm not sure what could go in it, being so small.. any ideas? How many fish could we have theoretically?
There some very good ideas listed , but the planted tank with some neons and tetras sounds real nice. If you go that route make sure you upgrade your normal lighting.
I would think that the tank you're thinking of would be way too small for congo tetras - but I'll let more experienced people comment on that.
I would suggest you get a bigger tank if you can, cos soon after most people buy a tank they tend to want more fish, and then go and buy a bigger tank ... and then another bigger tank ...
Killifish? They're good for small tanks.
Or if you want a planted tank and don't mind maintenance then maybe 3 dwarf puffers? 10 uk gallons should be okay for that, as long as you have good filtration.
