Top Ten List of Things I Wouldn't Put in My Tank

Based on personal experience, below is a list of the top ten things I wouldn't put in my mixed reef tank if I could do it over again. I realize people are going to hate, but these are just my views.

1) Green star polyps. While this coral is easy to care for and can add a unique (relative to other corals) look to your tank, it grows like a weed and is noxious to other coral species around it. I had this coral in each of my tanks. Realizing it has a tenacious desire to grow and move towards the top of the tank, I tried to isolate it from my main rock structures but it still found its way over.

2) Pulsating Xenia. This coral is interesting for about five minutes until (like the green star polyp) it starts growing like a weed and irritates the hell out of everything around it. To get it out of my 90 gallon, I had to treat it like some sort of evasive species and take extreme measures.

3) Mushrooms (primarily, Discosoma). Like the corals above, these are good beginner corals but they spread uncontrollably. I find they like to colonize next to my most expensive SPS and irritate them, and they are extremely difficult to remove.

4) Long-spined black sea urchin. Good workers but just didn't make sense in my tank. Constantly knocking things over, and I kept forgetting how close they were whenever I stuck my hand in my tank.

5) Green / Blue Chromis. I like the fish and have one in my tank. They made this list because they have a tendency to bully the hell out of each other until there is only one left "“ hence the reason why I only have one "“ the sole survivor.

6) Foxface. These are generally good workers, but they are extremely skittish and other tank inhabitants cue off it. Plus, I had one that decided to start eating all my LPS.

7) Powder Blug Tang. Love the fish but extremely susceptible to ich. Plus, 9 times out of 10 they are true bullies. This is one fish, however, I likely would put into a larger system.

8) Mandarin Dragonet. Like the PBT, I love this fish; however, they just don't really seem compatible with your typical home reef tank. I've never been able to keep these fish alive for more than a couple of years, even when I kept a good supply of a live food source.

9) Conchs. Like them but they don't seem to live long.

10) Filter Socks. Just because I hate cleaning them.

What would you exclude if you could do it over again?
 
Stylophora….all birdsnest…...they both grow too fast

pocillopora ….will pop up all over the place

Xenia and star polyps can be controlled/eliminated with very low nutrients
 
I would disagree with the conch, I've had mine goin on 8 years. The socks are easy, just don't use them. I gave up socks years ago and that removed my most hated chore.
To answer your next question, I notice no difference in water clarity!

Hi! Here is my list I learned over the years!

1. Six line Wrasse - gets way to agressive, never again!

2. All hermit crabs

3. Blue headed Wrasse or any other in the Thalasoma species - get large and eventually bully everything.

There's probably more.....lol....

Crabs, all, banned completely!
+100

2. Australian Sea Apple - I had one in my very first tank in the late 90s. Had no idea what I was doing. Kept the tank going wonderfully for 3 years. One night the sea apple died, got sucked in a power head and nuked the whole tank.

Great list! I agree with all of these except the crabs. I love emerald crabs. I would add galaxea and hollywood stunner, both of which kill anything with 10" of them. Nobody's going to list shark eggs? Thinking back I can't believe how much I saw those at pet stores.

I love Emerald, Porcelain, Scarlets, Hawaiian Zebra Crabs, I hate red and blue leg. There is a reason why they are cheap.
 
Along with everything listed above, I'll add pseudochromis, green "coris" wrasse, and palythoa sp., especially the green "texas trash" palys.
 
Clown and Sohal tangs, though they are stunning fish they almost always end up killing all tank inhabitants with maturity
 
GSP
Xenia
crabs of all kinds
starfish
large urchins
most palys, especially the green trash palys
almost all mushrooms (ricordea are a strong exception to that rule)
clove polyps
pseudochromis
....and probably a few other things I"m forgetting that cause problems more often than not.
 
Why all crabs?


I wonder the same thing. The larger emeralds and their likes I can understand, but tiny little hermits?


I've had the same handful of red and blue leg hermits in my tank since me coming back into the hobby about 5 years ago now. Not a one has murdered a snail for a shell, ate a dying/sleeping fish(and yes I have fish that sleep in the sand), killed each other for their shells, or any of the other things people seems to recall their hermits doing that puts them on that list.



Don't get me wrong, I realize every ones experiences are different, and every inhabitant can act differently in different tanks, but any red or blue leg hermit I have seen is a model citizen and a great part of the CUC.



Some of the other colored hermits I will agree on, murderous bastards!!


In my list:
GSP
Green palys
blue clove polyps(threw away 100lbs of LR from that crap)
mushroom of any kind with the exception of ricordia
frogspawn, Not typically considered invasive, but they grow so fast if conditions are right they smother any other coral it gets near.
 
Blue ochtodes. They took over like a weed.

Cleaner shrimp. They take food away from anemones and kill them.

6-line/8-line wrasse. Too aggressive.
