Hi im new to this site. i've had fishtanks for about 8 years with various fish from gold fish and mollies to oscars and loaches. ( not togethor of course) i started with a 10 gallon tank and i just upgraded to a 29 and a 30 gallon tank. im not an expert , yet im not a noob either. my 29 gallon has 3 angel fish, 1 opaline gourami, 1 powder blue gourami, 1 clown loach, 3 polka dot loaches, 2 long fin red minor tetras and 5 black skirt tetras. my 30 gal
has an oscar that was in my 10 gallon before i upgraded. i also just resealed an old 29 gal
with a slate bottom and stainless steel frame, not the one that im currently using. most of my fish knowledge revolves around loaches. now that you know a little bit about me i have some questions. 1. i recently noticed that one of my polka dot loaches flicks along the gravel. is this normal or is it a skin parasite? 2. how do i edit my profile?
