need nice colourful dither fish which will be able to survive with yellow labs in a 42 U.S. gallon tank, do you have any suggestions.i would be grateful for any information you could provide. thanks
How many labs are there? Labs are generally pretty bold fish that probably would fly to the rocks as soon as you walk into the room. If you do have a problem...the only thing I guess I would suggest in a tank that size is 4 or 5 giant danios (Danio aequipinnatus). They're very active and have a nice green sheen to them.
