i the last week fry have been popping up all over my tank and i now desperatley need a new tank so i am begging my mom and dad to buy me a new one but what i would like to know is how big should fry be when i sell them
The fry will usually only be bought by fish stores when they are 1 inch and even then most fish stores will only give you credit for them not cash because they can get them really cheaply in bulk from their suppliers from guarenteed disease free tanks, also a lot less effort for them.
I don't think you'll make much money (if any) off guppies...pet stores like william said have gauranteed disease free suppliers that sell in bulk. You may have to ask pet stores if they will take them. Guppies are very common. Good Luck!!!
