Hello everyone, I have a 3 year old 20 gallon long very very heavily planted tank. It houses 8 peppered corys, 7 harlequin rasboras and a dwarf gourami. It has three h.o.b. aquatech 5-15 gallon filters packed with extra bio-media. I was hoping to get a clown pleco to add to my tank since they are one of the very few plecos recommended for 20 gallon and up tanks however i've been unable to find any for months now. But I do see bushy nose plecos for sale often....I know the bushy nose plec is recommended to have a 30 gallon tank. However since a 20 gallon longs floor dimensions are the same a 30 tall I'm wondering if a bushy plec could be feasible in a 20 long? I've read conflicting info, some say a 30 gallon is recommended not because of the size of the plec but because of their large bio-load. Most people in forums say the bushy nose very rarely reaches over 4 inches in size. And since my tank has more filtration than currently needed as well as being heavily planted I'm wondering everyone's thoughts on adding a bushy nose? Below is a pic of my tank for reference.
