So recently two fish have completely and utterly disappeared from my 12 gallon fresh water tank. (trust me I've looked everywhere). I lost a Corydoras Catfish and a Red Wag Platy(Left by himself after my other Platy died a while back).
Here's what I have in there now:
1 Honey Sunset Gourami
2 Black Mollies
2 Corydoras Catfish
3 Fancy Guppies
I couldn't put my old/ a different Betta in that tank right? Because of the Gourami and the Guppies?
I'm going to replace the catfish but I was looking for a solitary fish I could add with out overstocking the tank.
Would a female Betta work? How about other solitary fish any recommendations?
