The basic rules for keeping fish successfully are :- 1 inch of fish needs a minimum of 1 gallon of water. :- Every tank needs a permanently running cycled filter. :- Every tank need at least 50% of its water changed every week. Follow and keep to the above rules and your fish stand a chance of survival. Fail to keep them and I can guarantee that your fish will be constantly getting ill and maybe dying. The species you named are all tropical fish and so you will also need a heater/thermostat set at around 78F to 82F. You will need a thermometer too to keep an eye on the temperature. Your tank is way too small for the kind of fish you purchased. Angelfish grow to around 6 inches tall in less than a year, and Clown Loaches grow to over 12 inches long in about the same time. You would need a minimum of a standard dimensioned 4 foot tank for that amount of large fish but it would be better if the tank was 6 feet long x 1.5 feet deep x 2 feet high.
That should be fine, but keep an eye on how the angels behave towards the gourami once they get bigger as they may bully it once they are full grown.
None. That's too small.
Mhmm, they definitely doYES! you definitely need a tank at least 75 gallons large.
You would need at least a 150 gallon tank
Not unless you have an 800+ gallon tank and even that might be risky.
It is not harmful. But if you want to clean up the algae in the tank you want to get a pleco. They are very peaceful fish and will not harm angelfish. I have a pleco and three angelfish in my 35 gallon tank right now and they get along great!
Angelfish are very aggressive fish. They are also very territorial. They want their own space and the whole tank if they can have it. I'd suggest that if you have a small 3 to 5 gallon tank you get a bigger tank as that size tank is too small for Angelfish.
You don't! What you do is get a 55 gallon tank because angelfish won't be happy in a 10 gallon tank, and then you take the betta out of the tank (it will fight with your other fish) and just get more mollies and put lots of hiding places in the tank so the babies will live.
they will do fine together just make sure that you have at least one gallon per fish! you could get at least six of each unless you want to put some others in there or if you already have some in there
Probably a large Cory catfish (they only get to 3-4 inches) so that it doesn't get eaten or attacked by the Angelfish. P.S. the Angelfish needs a tank of at least 30 gallons to be happy.
In a freshwater tank, you don't want more than one inch of adult fish per gallon. Angelfish can grow to about 6 inches and dwarf gouramis can grow to about 3.5 inches, so your tank can fit any combination that adds up to 28 inches of fish.
depending on whether you plan to keep them till adult hood a 50 g tank will hold 4 adult angels
