Hi guys! Want to have opinions on the matter. Right now, i have an Oscar, a JD, 4 Siver Dollars and 3 Severums, all juvies (1,5 - 2") in a 90 gallons tank. Cycled and plenty of filtration. Im plannig on building them a new acrylic aquarium when tje fish will reach about 5". Maybe add 1 or 2 SD more. The question : what tank size will be prefered for the when reach their full size? I was thinking 180g. What you guys think?! Thanks! Sry for my bad english, im french.
