This is a discussion on have 10 gal tank within the Freshwater and Tropical Fish forums, part of the Freshwater Fish and Aquariums category; -->
I have 1 dalmation molly, i want to add one more dal, 1 blk molly, two danios an bottom feeder,i also have two small ...
For that size tank, look for doing a species only tank, as almost every small fish is shoaling in nature which means you need a minimum of 6 of the same species (not, say, 2 of 3 different tetra species). It's possible to have a mid/top level fish and a bottom fish group, but only if they are all on the very small side.
You also need to find out your water hardness (known as GH for general hardness) to know what kind of fish you can stock.
The guy at the store told me 3 mollys would be fine as long as i do water changes an he also said something like i can also add a cory or oto fish he also said my water is fine he the one that did my water testing I'm new to this Posted via Mobile Device
I'm afraid they gave you bad advice, which is all to common from most stores. Most of the time it is just ignorance, employees who work at the store either just because it is a job, or because they like animals (which does not mean they know how to care for them).
This website has a pretty good set of profiles on the most common, and some of the rare fish in the hobby. You can find the link to the profiles on the blue bar at the top of the page, second one from the left.
You can also link to pages in the profile into your forum posts by typing out their name as they are listed in the profile, for example Common Molly. As explained in there, they should be in a 24" tank minimum, but a 36" tank is better.
Agree. The advice from stores is not always reliable.
BTW, tweet0302, we have fish and plant profiles, under the second tab from the left in the blue bar across the top of the page. Info in each includes minimum tank sizes, numbers of the species for shoaling fish, water parameters, etc.
