I've had mixed results with multiple wrasses in my 180. I envisioned having a rare wrasse dominant tank similar to ones shown on RC and utube. However, I've encountered so many issues with fighting, sex changes, personality changes, and carpet surfing that I'm beginning to question my strategy. Here is my story:
I first added a cheap six line wrasse to get things started, which was a no no. My second wrasse was an absolutely beautiful supermale Australian Scotts Fairy. He carpet surfed on day two despite having a six inch high barrier around my tank. I thought to myself, "wow, that was unfortunate and could never ever happen again!". My third wrasse was a large supermale Red Velvet Fairy. He carpet surfed on day three (so much for it never happening again!!!). The tank was then covered with a mesh. My fourth wrasse was a mystery wrasse. He was endlessly attacked by the ultra aggressive six line. I got rid of the six line to keep the $100 mystery wrasse. My next set of wrasses were a trio of flame wrasses including a supermale and two females. The male never paid attention to the females, which resulted in both females turning submale. The new submales attacked the supermale. I had to get rid of the supermale. After which, the larger male killed the smaller male. My next wrasse was a cute little clown fairy. Clown fairy's are known to be timid (keep this in mind for later reference). At about the same time, I obtained two supermale red velvets from LiveAquaria. One carpet surfed while in quarantine despite having a tight fitting top (
). The other made it to the big tank. After adding the clown fairy and red velvet to the main tank, the mystery wrasses started attacking both. The mystery wrasse was moved to my frag tank. Now, the clown fairy has started to attack my red velvet. I'm trying to catch the clown fairy as I construct this message
. I also added a supermale lineatus. He is doing well so far and appears a perfect addition.
Rules of thumb I have learned on wrasses -->
1. The least expensive & least desirable wrasse will always be the bully. Remove the bully and the next least expensive fish will become the bully.
2. Never purchase rare wrasses from low priced sources.
3. If you purchase multiples of the same species, then just purchase females. They are cheaper, can develop their own hierarchy, and live longer.
4. Add a bunch of wrasses at once instead of one at a time. I think the wrasse dominant tanks on RC survive because of the inability to pick on individuals. The aggressors can always find multiple fish to pick on.
5. Wrasses are individuals and have their own personalities. Despite personality trends being available, one can never predict how a wrasse species will behave.
6. Perhaps be happy with one nice male wrasse and avoid all the problems I've encountered
Note: I'm still learning and haven't given up yet. I just added two new female flames to my quarantine.
