well thats good news for me. I havn't tested my water in a while, but my guppies had babies last week and there are still at least 20 of them swimming around in the tank. and I think my other tiny pleco is still alive. I think it might have been sick, (dont have a Q-tank yet) thats my next buy once I get the 75 cycled. was hoping to grow out a bristle nose for a while with some clown loaches with the guppies in a 40 gallon. clowns are about 1.5 inches 2 of them, the bristle nose was about 3 inches, and like 5 adult guppies. the other pleco was about .5 inch to maybe an inch. and 3 apple snails, and one rams horn snail. everything else looks ok. the loaches are kind of acting funny, they swim a little bit and then the just float around. im getting my water tested in about 15 min. tank has been up and running with fish in for about 2 months, cycled before that. I started to slack on my testing cuz I got injured at work and ran out of testing stuff, and was having troubles getting paid for my lost work hours. but getting a new job should have next week and gona buy a bunch. thanks for the info and any more I should get.
