Are you tired of finding your prize wrasse or trigger dried up on the floor after a failed attempt of it escaping its reef aquarium home? Or, after searching the tank and then the floor for him/her, you finally find him in the overflow and spend the next 3 hours trying to dig him out? If you related, then this easy DIY reef tip and trick is just for you.
As reef hobbyists, we put a lot of investment into our fish and we want to keep them safe. Keeping them securely in their home is very easy and affordable. Glass tops become a magnet for algae growth and eventually start to block out the precious light to your coral. They also have a tendency to shatter, leaving shards of glass scattered around your tank. A canopy is nice, but its not an option for everyone. And, frankly, I have found fish stuck on top of the portion of wood that sits on top of my canopy. It also doesn't solve the issue of the fish jumping into the overflow.
For $15-$20 you can buy egg crate lighting from Homes Depot or Lowes and take the Kamikaze tendency out of your fish. Egg crate lighting is easy to cut and fit to cover the top of your aquarium. It will not block the precious light for your corals and you will not have to worry about algae build up. Most importantly it is an affordable solution for keeping your prize trigger or wrasse safe. With some zip ties you can securely attach a egg crate lid for your overflow.
Rule of thumb is that if you are going to have the same genus of tangs, you should add them at the same time or within a couple days before they establish their territories. But lets be honest. Fish die and need to be replaced, or we don't always have extra wads of cash and need to buy fish in stages. Here is a trick that I have used successfully to add .
Get some small mirrors (6" by 6") mirrors from Target or Walmart and place them into your aquarium before you add the new tangs to your aquarium. The existing tang will be more focused on the tang that looks exactly like him rather than the tang that is a similar species. You will need to keep the mirrors in your aquarium for a couple weeks as the new tang establishes their territory. After a couple weeks, remove the mirror and monitor the behavior of the tangs. If they start taking exception to each other, but the mirrors back in for another couple weeks. Eventually, the tangs will respect each others territories and live in peaceful harmony.
