Rotala indica and Crypto. wilsii

"I wanted to take the time to make some really positive comments on your tank guide! I've been keeping fish for a good number of years now, and while looking for some information regarding wet/dry trickle filtration tonight, I stumbled across your site.
I ended up reading your entire site! It's excellent! I only wish someone had offered this kind of knowledge when I first started! Instead, I spent countless time asking questions from about 6 different pet stores, trying to put together what they had in common advise-wise, and applying that. Let me tell you (which I'm sure you already know) many pet shops selling fish have uneducated people selling the fish, and it's rare to run across someone who truly knows what they are talking about. But page after page on your Site, I've found answers consistent to what I've read and learned that truly help someone that has a desire to actually keep their Fish healthy - not just set up a goldfish tank (not expecting the fish to live for a week), as some people do.
What you have created here is a comprehensive, accurate, and wonderful guide to anyone serious about fish keeping. I've already bookmarked it, and will recommend it to everyone I know that has an interest in the hobby!"

"I have been reading your page and I am finding it very helpful! Tank you (pun intended) very much for offering this resource over the web"
