You appear to have a light in your tank and also some bubbles. There is a product on the market called an "Ario" that has a blue/green/red LED light built in and a pump that creates alot of bubbles using a venturi.
ah sorry,i wasnt sure what you meant.no,i actually have a marine actinic light in the back and a freshwater tube in the front.the bubbles are from the spraybar connected to my eheim 2028 external.
just posted some pics.yes,its a male greshakei.maintenance is no different to keeping other fish really.a 40% water change once a week.decent external is a must really.not so important when the fish are small,but a must when your either overstocked,or,have larger africans.thanks for the comments exhiled.
