Vieja argentea

[jancibie]

Hello everyone, I wanna ask what is the maximal possible size(which you know) of male of Vieja argentae in tank and also in nature. I think that it should be 35 cm. Thanks.

My own argentea reached 13"/ 33cm in size, this took at about 4 years from a 1.5" size fish. I believe the fish would have reached it's maximum size if I'd kept him longer.

I see many videos and photos of large size aquarium specimens in the Dutch hobby.

35cm should be achievable with a large aquarium, good filtration and feeding.

Do you still think 35cm/14inches is achievable in a 75 gallon aquarium with good filtration, water, and feeding. I would think so just want to see what you members think.

75 gallon = 300 liters

That is way too small for argenteum

A 120 * 50 * 50 cm tank (4 feet * 20 inches * 20 inches) contains this 300 liters, and for a 30 cm fish this measures 4 L * 12/3 L (L being the length of the fish)

For argenteum you'll need 6 L * 3 L footprint

I have even seen an 18 inch Oscar in a 75 gallon. But I can tell you I was not surprised because of the maintenance that was dedicated to the tank. Now it is no question that it is not ideal to house them that way.

I keep bifaciatus, synspilum and argentea.
I'd say maximum size for a big male would be closer to 17" if kept in a larger, well kept aquarium.
180 gal 6' X 2' footprint or larger.
