Strong and Weak fish??

[Jen21]

I have mostly livebearing fish... swords, mollies, platies, and cats, algae eaters and two frogs in my tank. I was wondering if there are fish that you find more "stronger" or "weaker" than others. I had two neon swordtails, and they both died immediately. My platies seem fairly stable. Any opinions??

Hi Jen21

I think that it's not so much which fish is stronger than another, but which adapts best to the specific conditions of your tank.

You might also just have been unlucky with your neon swordtails. It could have been that they were becoming ill when you bought them.
