Corydoras species grow to around 2" (5cm). Your aquarium will actually be holding around 12 or 13 galls of water when you take into account the 1" at the top not filled and the water displacement from at least 1" of gravel (substrate) on the bottom. The basic rule for keeping fish is 1" of fish needs 1 gallon of water. If you do the sums you will see that you can keep a maximum of 6 Corydoras in the tank.
2 or 3
depending on whether you plan to keep them till adult hood a 50 g tank will hold 4 adult angels
Dpends on the size of the fish its one inch full grown for every gallon
Personally, I wouldn't keep anything in a 1.5 gallon tank. Not even a single Betta. I consider 5 gallons to be a minimum for a single betta.
Yes. to be accurate These fish should be kept in an aquarium with a sandy bottom.
Depends which tank.
ghost shrimp,
I would only keep one Tokay per tank, especially a male. They can be highly territorial.
it gets 26 miles to a gallon tank
I believe it was 13 gallons it is a 15 gallon tank.
2001 ford diesel has a 36 gallon tank
No. A 10 gallon tank is barely big enough to keep a single goldfish in.
