Over the summer, our kids acquired (5) fair gold fish which pulled me back into aquariums after being out of it since the kids were born (8± years). The kids are enjoying the fish but the tank is too small for long term projects.

I am looking for a set up that would allow for these gold fish to remain indoors until we build an outdoor pond, but also allow for future fish to take over the tank.

The set up could be complete or partial or individual components.

Thanks! Bernie
