Good for you getting a bigger tank!
Now what are you going to put in the smaller one? 40 ltr, that is about 10.5 Gallons for the USA people lol.
FW & SW
Favorite tank right now - 72G Bowfront Wadai Tetra, Cardinal Tetras, Ghost Glass Cat Kryptopterus bicirrhis and Clown Loach Cory haven
New to FW fish? First tank in a long time or EVER??? Need some info on keeping fish?
