First fish in the tank. Need advice

[Ssteve]

Cycled my 14g biocube for over a month now, all readings 0, water change done etc.. Then added a cuc, and five days later now I just added my first fish. A true perc that's very small.

My tank has a maxijet 900 and a koralia 240. After floating, and then a drip I placed him in the tank. Seemed like he was struggling with the flow a bit so I killed the pumped for the time being. I'm wondering if I'm ok without my return running for a bit and if so how long should I give it before turning on the return? I don't have any corals so filtration is really the only concern.

Started just the main pump back up so it filters, and I angled it up a lot and seems as if hes getting accustomed to the flow. Now he seems real puzzled by the emerald crab whech keeps trying to attack him, but he also seems to be taunting the crab.. Theres no chance the crab can get him while he sleeps is there? I feel bad for the little guy just turning all the lights out on him in this strange new place. Right now I just have my moonlights on, but I know he needs to get some sleep eventually.
