"Cycle" girl here: ;D :-* FINALLY I think I can celebrate that my tank has cycled! Ammonia ZERO Nitrates 5-10 NITRITES ZERO BABY! 8) pH 7.6 Thanks to the many suggestions of multiple water changes and AMQUEL+ (needed to use 3 doses to bring nitrite levels from deadly 5.0 + down to 0.50; nature did the rest)! I thank you and so does my fishies and my frustrated husband! Ok, now what to add? I can understand the rule of 1 inch/fish per gallon, but does that mean I can only have approx. 3 fish (have a 10gallon tank)? The adult molly size is 2-3 inches (although mine are only 1.5 inches). I only wanted to add a pitbull pleco (2-3 inches) and an upside down catfish (2-3 inches) in addition to my 2 surivivors (and let me tell you, they ARE survivors, living thru that mucky water), and POSSIBLY an additional molly (I really like these guys!). Also, I was going to look into adding some shrimps (looking at red cherry and bottlenose) they are small under 1inch, how much do I have to take them into account? I have an algae problem and wanted to take care of it naturally. I most likely won't get the pitbull pleco for a couple weeks; have to find out if my pet store can get some in! And one more question; I keep reading that the upside down catfish needs to be in a "school" of them, but the pet store I started using (I would call them reputable) said there's no need to. I have also read some other websites that they are fine solo. Anyone have any experience with these guys? Ok thanks!
