So my girlfriend bought a 29 gallon biocube from Ocean Treasures a couple of days ago and I took rocks, sand, and water from my 240 gallon to start the tank off. We then went and impulse bought an octopus. he is so tiny. we named him squidward. We felt that it was a great name for our new friend. So far he has eaten an emerald crab the first day and 2 red crabs today. He doesn't seem to find the damsels we put in interesting at all. they are freaked out about him but does not eat them. he jumps on crabs though like it is the thing to do. Yes you might say that it is too soon to put anything like this in a tank so new, but mind you that everything in there came from my 6 year old established 240 gallon reef tank. We did this with her 12 gallon JBJ nano DX and we put in corals and fish the next day after start up and had no problems. That tank is about 6 months old. We take pride in maintaining the little tanks since its so damn easy to do so compared to my 240. What's a 5 gallon or 2 gallon water change every couple days? Really though. Too easy. Anyway all we need is a big yellow sponge and an orange starfish and we will have our very own bikini bottom. here are some pics of the 12 gallon and Squidward in his 29 gallon. oh check out the video of him taking down a red crab. First pic is the 12 gallon. hope everyone enjoys this.
