It's best to buy a plec only after the tank has finished cycling. To be safe, wait for 2 months after tank has cycled. Plecs aren't that hardy at all. :nicefish:Deefish said:How long should you wait before introducing a pleco?
It all depends, there are different types of GN (L-18, L-81, L-177). The L-81 is supposed to only get about 7.1" according to PlanetCatfish. If I remember correctly, the one with the smaller spots are sensitive to tank conditions, so they should be added in a mature tank. Don't ask me which one is which, since I have a GN and have been told it's an L-18, but looking at some of the pics on PlanetCatfish, it also could be an L-81. I've had mine for about 5 years and it's about 4" now. I bought it when it was about 3" or so.Deefish said:Thanks Blue. I think that I should have picked a smaller pleco as I have only a 20 gal tank now. I saw someone on the forum stated that a "candy" plec would be good for that size. I will certainly wait but perhaps you would recommend a different variety than a gold nuggett. I didn't know that they grew to 18 inches! Deefish
