Hi. I'm just an old lady who just found out she loves aquarium life, but apparently clueless and impatient and feeling really bad for my 10 gallon inhabitants. It started with rescuing a beta from being flushed. That poor beta went into a 1.5 gallon fish bowl to a 10 gallon aquarium that wasn't cycled 'cause I had no clue. Pet store associate set me up with an AIR PUMP, gravel and some fake plants for Mr. Beta to hide in.... I just assumed the guy knew all about keeping everything aquatic happy and healthy. I ended up with a dwarf frog too (which I fell in love with and bought 4 more then next day). Mr. Beta survived the whirl wind air pump which I took back the next day and found a filter system, proper food for both frogs and beta.... well .... He did eventually die and now I have 2 cory cats, 3 neons, 2 apple snails,3 sword tails and 2 frogs. I'm getting a 20 gallon or 29 gallon tomorrow. NO plants at all, just aquarium decorations for hiding in and around for everyone. All this in 9 weeks. I DID NOT WANT ALL THESE fish, they have been gifts, handed to me in bags :/ tonight one of the snails is floating. They've been in there probably 3 weeks, pretty good sized now. What might be causing it to float? The PH dropped a little today, but it's back to 6.8 again.
