CA for a 20 gallon

Are CA and SA cichlids pretty muvh the same or are they different? Because i would go for SA if there are different choices.
 
They are quite different: most SAs love acidic water, and most CAs love basic water. Go over to the species profiles here and see what you can find that lives in each place! :D
 
One big advantge to SA's over Ca's for the smaller tank owners is that there are allot more SA's that will go into a tank that size as opposed to CA's. Most CA's are big fish.

The water conditions are allot more forgiving with CA and SA cichlids. They can live happilly together in a tank.

The sight variation difference in water types is not big enough to cause the fish any harm or discomfort.
 
Discus would absolutely not work in the tank you are describing. I would suggest that you look at Aequidens curviceps and/or Aequidens dorsigerus as very attractive and practical alternatives.
 
Concur. Discus are not good when kept solitarily or only in a pair (one becomes dominant over the other) and your 20 gal probably doesn't allow for the smaller of those two options.
 
aequidens are acaras right? because u saw an emarald acara and that was the second thing i was going ot ask. I really didnt think the discus would work but i was just making sure.
 
The two species I mentioned are in the acara family. Well, given the number of species that get reclassified at one point or another, they might NOW be in a different family, but at least they USED to be acaras. In any case you can find a lot of information about them under the names I gave.

However, I should note that they are much smaller than the rest of the species, and that is what you would need for a tank as small as a 20 gallon. Not as small as dwarf cichlids, but much smaller than the average acara.
 
Anything still in Aequidens is a "true acara." However, all cichlids are member of the same family, no matter what generic name they have.

I believe, though, that each of those two is a member of the genus Laetacara, the so-called "Smiling Acaras."
 
Thanks for all of the help;)

Someone on another site said i could keep a jack dempsey. A far as i know these are really aggresive and get pretty big. And i also thought that it was like 50 gallons min for these fish. Just making sure:)
