I have a fish who got sick and his plants had to be out of the tank for two weeks. I don't have an extra heater so they were kept in a bottle in room temperature. They're finally safe from having Ich, but they don't look so good since they weren't in the heat. Is it safe to keep them in my tank? I don't want my fish or the other plants to get sick from it. I put it in the tank with aquarium plant food from API. I just want to make sure I'm not going to get my fish sick or ruin the other plants.
I'm adding a picture, they're the ones in the back.
