Stocking Advice Needed!

[Robert_Popa_918]

I’ve got a 160 gallon fish only tank that has been going for 8 months now. There’s currently a foxface, young Koran Angel, and 3 clownfish. I stopped adding fish to the tank roughly 2 months ago due to water quality issues. My levels are now back to balance and I’m trying to add a school of 5 blue green chromis to the tank. The thing is that I’m not sure if my biological filtration can handle 5 new inhabitants. I need some advice on wether I can add all of them at once or not? I’d really like to add all of them in at once rather than purchasing them in smaller groups of 2 and 3 over a period of weeks. Any advice is appreciated!

I would think a tank that big will handle 5 chromis ok. I have a 75 and have added more at one time once water was established and had no issues. But I can tell you chromis will kill each other until there is only one left. Our only survivor is called Highlander!

Really? I thought that chromis were supposed to be like one of the most peaceful saltwater fish. Have you had experiences where they go after your other fish?

Nope. They are and were model citizens. Very peaceful to all my other fish. But after I put 4 in, they slowly killed one by one until only one remained. I was surprised so then I started searching for that in the forums and it seems to be a common experience with many people here in the forum with chromis.
