When is the bioload too much?

[Blazer88]

I have had my 65 up and running for about 7 months now (rock was from established tank) and I am wanting to add two purple firefish into the mix. I currently have:
Kole Tang 4"
Coral Beauty 4"
2 false-percs 2"
Bi-Color Blenny ~3"
Yasha Haze Shrimp Goby ~2"

My tank has some GHA but it has been vastly improving over the past few months. I figured this was normal since the tank was fairly new. I am using a 15G sump/fuge and I have to trim my macro every other week. I am consistent on my maintenance and do a water change every other week. I also have a large skimmer (CSS 220) to keep the water clean. My water parameters have always been stable with zero nitrates, PO4, or ammonia. I am thinking my tank could easily handle the extra bio-load produced from the firefish, but I also want to make sure the current inhabitants would mix well. Any problems adding the firefish last? We have a local meet at a LFS on Saturday (3 hours away) and they have the firefish for $20. Thanks for the help.

I would say your at the max. IMO

When I think about it, I think you are correct. My GHA is finally going away and I would hate to add anything that would encourage more growth. We'll see of my Coral Beauty turns into a nipper or not, that would clear some space for the firefish. Thanks for the reply.

You should be fine purple firefish aren't going to add much to your bioload. I have a 65 gallon with a large bioload but no algae problems and no problems with nitrates. I think you can put a few more fish in.

Sure, put him in. Not a big enough fish to push you over the edge. IMO
