    Hi Reefers,

    newbie, and need some help.

    I have a red sea 130D, with a fish and corals. My temperatures are good, usually have the aircons on, lights recently replaced, and my corals and other fish are doing very well. I have good growth and colour on my corals.

    I recently found that 2 of my 4 chromis were spending lots of time on the surface of the water, and they seemed to be having difficulty swimming. 2 weeks later, both have passed on.

    My 2 african clowns and goby are doing very well though.

    Any thoughts ?

    my ph is 8.4, salinity and other parameters are all fine.

    How long has the tank been running and can you give the readings of the other water Parameters...ALK, MAG, CAL...extra info will help to figure out what could have caused it...maybe it could just be pecking order or maybe something more serious..the more info, the better we can try and determine the cause..

    Chromis are well known for picking on and killing the weaker ones in the group, they won't stop until only the stronger ones are left or they feel they've reached some sort of balance or pecking order or something.

    I agree with Viper357. Like many shoalfish, Chromis have a very cruel way of picking off the weaker/smaller ones in the shoal. I started with 5. And only the biggest female is left.

    I started with 5 and a year later I have 4.
    They are now all big and mean and evenly matched.

    I'm having a chromis fight evening this weekend. All reefers welcome, bring your own meat and drinks

    I had five. The 2 killed the rest and then killed each other. They are more like temporary fish

    Hi guys,

    Im in the process of stocking my tank, and seeing as chromis are "temporary fish" what other options are there to a small shaol of fish. I was thinking blue damselss but not sure if they will do well in a shoal due to territories, was thinking they will be to concerned fighting amongs themselves to worry about the other inhabitants, any one has experience with more thatn 3 blue damsels.

    Does each one steak out its spot and defends it aggressively, or will they shoal?

    You can keep yellowtail damsels (Chrysiptera parasema) in a group (they actually prefer it).

    Our local chromis (C. nigrura) does well in a group if introduced at the same time. Can be tricky to catch 5 on one day though. They're quite sneaky sometimes:

    Flasher and fairy wrasses are also excellent in a group. Finding female flasher wrasses can be a real pain, unfortunately. Female fairy wrasses are a bit easier to find, if you know what to look for. Keep in mind LFS usually list the females as a different species and they're usually about 1/3 the price of males. If you don't want to fork out for a male then just add 3 or more females and one will change to male. C. solorensis is one of the more common ones:

    Well I'll be damned, I have a female solorensis.
    Now I just have to get it to come out the closet.

    As you say, dirt chreap at the local pet shops.
    They dont look that fantastic in the holding tanks. Mine was called a ruby head fairy wrasse on the list. I'll definitely be trying to find it a partner, the male is stunning

    Yep, female solorensis usually go for about R120. Males R450+. Kinda makes sense though because in the wild the ratio is about 1:10 males to females. Just wish LFS would import female flasher wrasse now...

    As a preference, I like females.
    In this case however, I prefer the male;)
