is it ok to only have 2 siver dolars in a tank?

Question

in a 20 gal

how many can i keep in my 20 gal??

Answer 1

Silver Dollars are schooling fish, so they really should have at least 5 of their own species or they will be in a constant state of panic... You may be able to keep two Silver Dollars alive, but they will certainly not be at their best, they will be stressed, and you won't get to enjoy much of their natural behavior... At 6 inches each, 29 gallons would be a good minimum to set as they are active swimmers...

EDIT: For the reasons I listed (schooling habits), you really couldn't keep any. If you want a similar looking fish that is smaller and would be perfectly at home in your tank, try a school of 5 Hatchetfish... They also have very deep bodies, but stay 1.5-2 inches...

EDIT 2: Yeah, Confused, that's exactly why we put our initials... forget the fact that, if we were so inclined, there are other ways of finding out whose answer it is, but it is, of course, so we, and our posses can vote for eachother... If you are wigging out because you think somebody is cheating over points, which as it turns out, are worthless, you may need to log off of Y!A for a while.

Answer 2

****, I'd have to agree with soop, after looking at the last question as well. What you've really got the problem here is spacial limits. Confused is also partially right as well. If you consider with African cichlids, many tanks are overstocked. This is done to limit aggression. Heavier filtration is also needed to assist this. However, what soop is saying, and I agree, the problem is the spacial limits of a 20 gallon tank for a fish capable of growing out to 6 plus inches.

The SD's wouldn't have the proper space to thrive. Now if you are asking can you keep young or juvenile SDs in a 20 while you got a larger more proper tank, sure, and that would be a good deal. I would not think of a 20 gallon tank for long term, despite however many place you might see doing it. Err on the side of caution here please.

Answer 3

if its at least a 20 gallon tank,2 silver dollars will be fine.

As always nosoop exaggerates everything he has ever read.And has no real experience with these fish,through friends,or by owning them himself.

Yes they are schooling fish,a pair will live,by them selves,in a 20 gallon just fine.I have a friend who has had 2,still today even,and has had them for 8 years now.They are the only fish in the tank,so being insecure around the other fish is not the issue.

They may do better in larger schools in larger tanks with other fish,but 2 in a 20 gallon will be fine.



I also find it interesting how all the so called "top contributors"end there own answeres with either their initials or by signing it themselves.Could this be so they can vote for their own best answer?Without confusing it with the other,better answers,that are not by the "top contibutors"?

Answer 4

they will be fine but they like to be in large ropus and large gropus means large tank provide at least 55 or 75 better
and there are many silver dollars kinds i like the one with the black bar on the sides and they are expensive

Answer 5

yes,but how much room do u have?believe it or not silver dollars do grow fairly big
