Okay, recent events in the tank have given me cause to ask these questions. First, one of my green corys (the smallest I think) has been hiding a lot. I have two rocks that lean together to form a cave and he wedged himself between one of these and the gravel. I had some trimming to do near there, so he swam away when I got close, but soon after I was done he was right back in the same place. It has me really worried. Also, I have noticed some snails in the tank. Yes I know that some snails can be beneficial, but these came in with the plants (even though I tried really hard to make sure that I cleaned the plants of all snails and snail eggs). I am considering a betta to aid me in my attempts to wage war on these shelled pests. I have also noticed some algae growth. I'm not sure yet, but it might be of the hair algae variety, and depending on what it turns out to be, do you think it would be worth it to get a SAE or an ottocat or two? I would really like to not overstock this tank, and am very hesistant to add anything else. I mean I would love to add more fish, but I am afraid of overstocking the tank. Oh well, I also don't want to lose my live plants to those damnable snails. Any advice you guys could give me would help.
