  1. Default Converting tropical aquarium into goldfish aquarium

    0 Not allowed!
    This is my first thread, so bare with me - I have had a freshwater tropical aquarium for about a year now and want to convert it into a goldfish tank - I just have two major dilemmas standing in my way:

    1. I would like to keep my rubber lip pleco (I have done a lot of research and think it will work - if not, I can always remove him later, but would really like to try.)

    2. I want to remove all of the gravel currently in the tank - I have read it is a good idea to syphon it out, but my syphon is not nearly strong enough to do that - could I just scoop all of the gravel out?

    I am really excited about keeping goldfish and have been researching like a crazy person - I want to take all my steps slowly and intelligently as to avoid as much disaster as possible - any suggestions would be appreciated.

    It depends on your home, but the difference between tropical fish and temperate fishes, like goldfish, is the heater.

    If your house doesn't get below 66 or over 77, you could keep goldfish just fine. Best temperature for them is 68 to 74.

    I used to use those big plastic cups you get at fast food places to scoop out the gravel. Why remove the gravel at all?

    Common goldfish, like Comets, grow to 14 inches long, so you'd need at least a 6 foot tank to keep them.

    Welcome to the forum, by the way.

    Agree with everything Dave offered up but check my goldfish link in my signature to look at the size goldfish grow to. Best to stick with some of the smaller fancies.

    I just used a square Glad container to scoop out my gravel.

    Thank you both very much! Removing the gravel was just for aesthetic realy -Lady Hobbs, do you think I could keep two or three facnies in my tank? Maybe a black moor, a ryukun and an oranda?

    You didn't mention the size of your tank but the Moor and the Oranda get very large. 10" and up.
