I'm planning to add guppies in my 23gal, and maybe a malaysian trumpet snail or ghost shrimp. Will 8 guppies be allright? Or will I get oversticked? My tank stats are in my sig.
I don't know if I'd risk Guppies with Serpaes. The Serpaes may have been fine with the Platies, but male Guppies have long flowing fins which Platies do not have. And those fins will be a target for the Serpaes.
Edit: Also, if you wanted to get Guppies, I'm assuming you wanted males and females? If you have females, you'll get lots of fry. The Serpaes may eat some, but you'd need to be prepared for some to survive. Which means your tank may get filled up quickly...
