Hi,

I was wondering - How many fish could fit into a 70 gal tank? I know that only 7 goldfish would fit in, but how many would I be able to fit in with either
1. A Tropical 70 gal tank
2. A coldwater 70 gal tank

The answer REALLY depends on the fish you want to put in there. It could be 1, or 100.

Hmm, interesting - I noticed on some of the members photos that they have over 40+ in a 70 gal tank... What kind of fish would you recommend?

Are they alive or have you run them through a blender?

Aquascape? I'm a crypt farmer.

It's a fine line between fishing and standing on the shore looking like an idiot.

That IS an aquascape, it's titled "The Vacant Lot".

Depends on your preference...

Personally, I prefer shoals of smaller fish over a few big monster fish, but others prefer the big monster fish. Take a look at the fish galleries. If you see something you like, research its requirements and compatible fish. Also make sure they are "plant-safe" if you plan on keeping a planted tank.

I'm sure some of the more experienced community-tank keepers will tell you about maintaining balance at the bottom, mid, and upper water levels. I don't know enough about community tanks to comment on this.

A cooler water tank MIGHT be able to hold "more" fish (since O2 will dissolve more readily in cooler water...I think...), but the species choices will be more limited. (Some day my chemistry teacher from long ago will find me and break my legs.)

Anyway...figure out what you want and then come back here for advice.

Go with small fish, They aren't as messy I have about 30 small fish in a 55 gallon and it isn't crowded. Neons, cherry barbs, danios, Ottos are good choices, plus if you have small fish then you can probably add some ghost shrimp or amano or cherry shrimp if you can find them.

Actually, 7 goldfish wouldn't be very comfortable in a 70 gallon. They get too big. You could pull it off with overkill filtration and fancy goldfish (they're smaller and less active than sarasas, comets, and commons) but you still wouldn't be able to put in any decorations or they'd be cramped. It would be more trouble to maintain than you'd want.

And plants with goldfish? It can be done, but not in a heavily stocked tank like you're talking about. A few goldfish can be trained to leave plants alone, or plants can be situated in safe areas. But a huge crowd of goldfish will bump into plants even if they don't want to play with them.

I think you should go tropical because there is a better selection of midsize fish and plants, and you can fit many more into a tank. Angelfish are easy and get decent sized without being messy. Gouramis as well.

If you really want goldfish, get about 4 fancy types for a tank that size. You'll still be able to decorate it some and the fish will be happy and it won't be impossible to maintain. And they will be even happier if you DO heat it. Goldfish don't really thrive in cold cold water--at least keep them the temperature of your home, if not as high as the low 70s.
