Hi, I'm new at this forum thing so sorry if this isn't posted on the right category I'm learning. Ok so I have had a 30 gallon tank for about a year and a half now, and it has been a rollercoaster, and mostly because I used to be a slacker and I never did water changes and new nothing of the nitrogen cycle. I shouldn't have had an aquarium that size but I've learned now. Weekly water changes and tests are being done, plants are growing, and cycle is now about midway. I am now starting to consider what to stock it with to prevent overstocking. I am also planning on getting a marineland emperor 400 to replace my aqueon quietflow 20. Of course I will have to re cycle the tank again, but it is worth it. Ok sorry I typed too much. So what would be a good species of fish for a community tank?
