What Size Tank Should You Keep Goldfish In?

How To Keep Goldfish Happy – All About Their Tank – Bigger is Better.

Outlaw the Goldfish Bowl

Invest in at least a ten or twenty gallon system. The bigger the tank, and the more aeration the fish get, the happier they will be, the more active they will be and the easier it will be for them to grow big.

Filtrate with an Undergravel plate driven by a single powerhead, or with a sponge filter.

If used, make sure the powerhead runs Venturi-style, which aerates well.

Supplement the efficacious filtration of the undergravel with a sponge filter like the Tetra Brilliant sponge filter. Hang on filters with pads and such are a nuisance to clean and have limited biological surface area.

Of course, Wet Dry trickle systems are superior, but they are correspondingly expensive.

Make sure the PH is buffered to neutral, there are chemicals for this. One superb compound is SeaChem’s Neutral Regulator.

Invest in some live plants. **Aponegeton**, Anubias, Cryptocoryne, **Pennywort**, etc are all good ones.
Anachris, Cabomba etc are a little messy and like cooler water. If you like fake plants, like I do, you can use most of the fake plants from Michaels. People talk about occasional fish toxicity to those but in recent decades, they have had to make the fake plants chewable by human babies without dying. So they have. And I’ve used a LOT of fake Michael’s plants. Check this out:

Almost every plant in this tank is a fake from Michaels and was made for flower arrangements.

Feed a good small pelleted food like Hikari twice per day.

Perform water changes every week or every other week. Use a siphon hose to clean the gravel periodically.

Did you know that a Goldfish can grow to be 8 inhes long in a single season (one year) if fed well and given enough space?

*LET ALGAE GROW ON AT LEAST ONE PANE OF GLASS IN THE TANK*, Algae reduces nitrate accumulations and is a big healp for Goldfish tanks.
