Columbian Tetra's

I have found Colombian Tetras to be somewhat nippy, particularly in small numbers. They're not in the same league as Serpæ, but I gave mine away after 4 months. Both the Colombians and Harlequins should be in groups of at least 6 fish.

I wouldn't keep mollys with tetras or Rasboras. Mollys like some salt in the water, tetras and rasboras do not.
 
I have 10 harlequins and 6 tetra's, mollys were a rescue fish(some idiot of a m8 of a m8 was going to flush, my m8 brought them to me to save them), may be moving them to another tank, as i think one may be pregant, not sure how to tell with mollys, first time ive had them

Cheers

The thing with livebearers is unless scrupulously careful, the females are almost always pregnant.

Livebearers and enplanned parenthood, exactly why I don't do livebearers.
