I was told by my LFS that they like to "school", so that's why I thought two shiners weren't enough to make a school.

Yes, they do, but fish generally like to shoal with their own species, and they will have a much better quality of life if they are allowed to form large shoals, as they do in the ...

I'm not convinced that shiners ( Notropis ) are suitable for such as small tank either. It's too cramped in my opinion, for an active cyprinid reaching 8cm.

Sunfish ( Lepomis ) are also a bad idea, as they are not small either.

I'm not sure what species "dace" are, but these are likely to also be ...

The eartheater will grow to about 10". Whilst temperature may well be quite wide range, they are certainly NOT suitable for a small tank - the recommended base area for this sort of fish is around 5ft x 18".

If you are keeping shiners happy and healthy, then these should be okay. Provide lots of oxygenation.

Eartheaters - geos and satanoperca - like it warm... around and above 80degF. So keep an eye on yours...

Hi Wrasse - the Pearl ...

I selected the cold hardy geo that likes temps down to mid sixties (Geo. brasiliensis). I plan on giving him away to my boyfriend when it ...

I just started a new tank (12 gallon Fluval Edge) & will not keep a heater (it will get high 60's in Winter & close to 80 in Summer).

I have cold water fish (2 shiners & will add 2 dace). I have a small earth-eater cichlid & will add a small sunfish.

Currently, there's no algae because it's a new ...
