I always stick to posting about what has worked for me or my experiences. If someone has a question about plants for instance, I don't give advice because I don't keep live plants. Shrimp. Snails. Frogs. Live bearers. Goldfish. Etc. If someone has a medicine question I can tell what's worked for me, or cichlid aggression etc. But I recognize every aquarist is different and every aquarium and every fish too. So what's worked for me may not work for the next person and vice versa. This is a place to share your experiences and personal knowledge, not belittle or put down others posts (not saying that's happened here, but it has happened to me on other posts). We can disagree, but base your disagreement on your own experience, not what you think it's the right thing because you are always right in your mind
