Adding color to tank

[nachosNcheeze]

Hello! I have a 75 gallon marine aquarium and i need to add some natural color to the tank. Unfortunately I’m limited on what I can get due to the assortment of fish I own. I have 3 Green Spotted Puffers, 1 Saddle Puffer, 1 Lawnmower Blenny, 1 Foxface Rabbitfish, and hermit crabs and turbo snails littered throughout the tank. I keep my water at 1.023 and have a skimmer and canister filter on. So pretty much, I just want to entertain some ideas on how to make this look livelier without having to add in decorations. All suggestions appreciated! Below is a picture I took of my tank just a bit ago. Oh yeah, one more thing, my wife claims that our tank is at full capacity... I say we can add another small fish or two. Who's right? lol

You could try some of the nastier-tasting corals like leathers. Most are4 tank but some come in yellow & they have cool shapes. You could also try mushroom corals, they come in all sorts of colors. You just never know with puffers though... they could eat anything. You could also try those fake corals--very colorful!

I think your tank is overstocked though.

Yeah, I agree. Don't fox fish get fairly large? I'm surprised all 4 puffers are not trying killing each other! LOL
Those gsp's can reach 6"+, Over time, that tank won't be able to sustain the bioload, and they will be cramped which can increase the likelyhood of aggression. Unfortunately, that can happen at anytime without warning too, even after years of peace, and could be fatal
If you are very attached to the fish, might you be able to set up another tank or 2 to spread them out?

I also like the idea of fake corals and fake anemones, they have been making some very attractive ones recently, not hokey at all.

+1 on the tank being overstocked. as the fish mature, the population will be reduced, either by the fish or by you.
