my opaline gourami... he was the first tropical fish i bought and this was last july to go in a 10 gallon tank, that poor thing went through hell, the cycling process on the 10 gallon and a lack of water changes before i was educated about it. by the time i learned about all the proper care i upgraded him to my 45 for a few months until i got my 75 and eventually he went in there to live like a king for the mistakes i had made when i first got him. well, when moving around some stock a couple weeks ago i had put some of them in a large tote before i had to go to my girlfriend's apartment for the night. i came back the next day to the poor little guy stiff on the carpet, it was tough.
