Wow Vicki, I'm so sorry to hear about all of your troubles! And especially the fish losses, it's always hard.
But you are also right that it's a learning experience, we've all made mistakes and learned from them, it's just a part of this hobby unfortunately. I'm glad you see it as a learning experience and are willing to move forward and not give up though, because I bet this tank will be stunning when it's done!
I really can't wait to see updated pictures! It sounds like things are finally starting to pull together which is good to hear!
Also, let me know if you want any Endler or hybrid females, I'd be more than willing to pass on my guppy female to you as well
