Hey there, as someone who also has had harsh treatment on another forum myself I can assure you that you will not find that kind of negativity on Fishlore. I joined this forum a little over a year ago and you can see that I have gladly become part of this welcoming and friendly community as of now because of the positive atmosphere.
On Fishlore, we all know that everyone begins their fishkeeping hobby somewhere and mistakes will happen. We all are constantly learning more and more each day on Fishlore ourselves and are more than happy to invite you to learn more about this amazing hobby alongside us.
Feel free to ask as many questions you need and don't hesitate to share us your current setups, we all would love to see them.
