Would a 3 gallon be too small for this?

I use 5 gallon and 3 gallon..........both are fine. I happen to like the 3 gallon better, because it's easier for me to handle. You'll like it!!!

It should not be a problem as long as the diameter of the jug fits.If you use the same size jug and just the smaller bottle of water it will be fine.

I do not think it would hold up on a 3.5 gal. particularly if its a round unit

I would say that a 3.5 gallon tank is a little too small. The main problem is that a goldfish is a cold water fish which does not require a heater. These Mexican dwarf CPO crayfish should be housed in a heated tank the same as you would keep tropical fish in. They don't share the same temperature requirement. One or both of them are going to suffer if you house them together depending on the set up.

My guess is that you could find a way to shorten the piece of plastic pipe that extends into the water, and thus make this pump work with a 3-gallon jug. The pipe that comes with this unit is designed for a 5-gallon jug ... and I wish you the best of luck in making this work for you! :) I am VERY happy with this pump!!

I have only used 5 gallon..I would assume you could use a 3 gallon as long as the three gallon is tall enough so the tube that draws the water up into the unit can fit..the tube is as long as the height of the 5 gallon bottle and not adjustable. .hope this helps

I don't know. But I woudn't keep anything in a tank that small. Maybe a few Ghost shrimp, that's about it.

This is designed for nano or small aquariums with up to 200 liters (55 gallons). It would be too small for a 75 gallon.

I wouldn't hesitate; a full 5-gallon bottle is heavier than your 3-gallon glass bottle. This stand is really strong anyway.

I would put drinks, a lamp, or food on it, but a 3 gallon fish tank might be risky. It's not a large surface. I would put a fish tank on a larger surface that couldn't get knocked over by accident

Yes. I have a 3 gallon and I think it is a bit too warm at times. It works well though

The mini works good with a 5 gallon tank and would probably be fine for a 10 but it may be slow. The small may be a better fit for bigger tanks.

I think it would be perfect if it will fit. I have a 3 gal and it doesn't keep it warm enough.

Probably be Ok. You can try then add the five or nine gallon tank in-line. Depends on your water used.

The 5 gallon water will be too big to hold for the porcelain water vessel. the 3 gallon is just perfect.

I have a small square 3 gallon tank and it just sits right on top of that fine. Hope this helps.

possibly, it's pretty big but it will likley do fairly well. In a 10 gallon it takes up 1/4 to a 1/3 of the space.

I have a 36 gallon tank and, although it works, it does a minimally good job. You need a commercial system.
