If your tank is a 10 gallon (filled to the brim) tank, it will only have about 8 gallons of water in it under normal conditions. The maximum amount of Corydoras you should allow is 4 because the rule is 1 inch of fish needs a minimum of 1 gallon of water. (Corys grow to about 2 inches plus). You will also need a 24/7 running filter and the tank will also need to have at least 50% of its water replaced every week.
1, and not for long. They get big fast, at least 18 inches, 2-3 feet more common.
None.
Technically, a 2 gallon tank for one Cory cat, 4 gallon tank for two Cory cats, and so on. The rule is one gallon per one inch of fish and Cory cats can grow to two inches, although the bigger tank the better. I would DEFINITELY not recommend a 2 gallon tank with one Cory cat. They like to be in groups and will be happier and healthier.
As long as the tank water is clean, and the fish are being fed properly, the catfish may just be entertaining itself by swimming that way.
I would recommend any of the Corydoras sp. for a small tank.
A extra large Green Cory Catfish can be as big as 1 to 1.5 inches from tip of mouth to tip of the tail fin. They are non-egressive and their mouths are small so unless you are keeping them in a tank you are raising fry, then all should be ok.
The fish are not bad together. But way to many fish for a ten gallon tank. You put one fish for every gallon. They will probly do fine but you will have to clean more.
Almost no fish can live without a pump. Unless you don't care if it live do four hours. A catfish can live in a 5 gallon tank for maybe a month. Then you would have to buy a bigger tank. The smallest catfish grows to about 5-6 inches. A good thumb rule: 1 inch of fish per gallon. I hope this helped! :):)
Can you have three pictus catfish in a five gallon fish tank
Cory Catfish tank mates include most community tank fish as long as they are non-aggressive and friendly in nature. Otocinclus Catfish, Tetras, Swordtails and of course other Corys can be a good fit.
Yes. Both are peaceful fish.
Yes it would. Generally any fish will live in tank so long as the environment is correct for that species. Catfish are pretty tough and should be OK.
Bristlenose catfish
For the 32 gallon fish tank, a general rule of thumb is one fish per gallon. The size of your fish makes a big difference to. The bigger the fish the more room its going to need. Your tank sounds a little crowded. I hope that helped you out.
