  1. Hi All,

    I have 5 compressiceps (2m 3f) that live in my 1200L with lots of other small tangs

    In the last few weeks 3 of them have been progressively sitting on the bottom more and more.

    They rest on their fins and breathe heavier than the other fish.

    When they do go for a swim it takes more effort than it should.

    I have done water changes and increased aeration but no change.

    The other 50 or so fish are fine.


    I think swim bladder issue? but why only the comps? and why not all the comps?

    Anyone got any ideas?

  2. After lots of planning, and having smaller tanks in rental properties, I have finally got fish in my new display tank.

    I have spent so many years trying to stuff large fish into the minimum tank they can be housed in and wanted to do something different.

    The aim was to make a beautiful piece of living art for the house and have many small fish in a large tank.

    I have done a lot of reading on this site (member for 14yrs despite very few posts) and also some SW reef sites and thank you all for the information so generously given.

    The background took a long time and the first fill was pretty scary but it held.

    I have an waste water pipe that runs under the floor and into the garden so no buckets in the house.

    The budget was around $5k including fish and panels for the stand to match bookcase.



    Tank: 7x2.5x2.5 from Abyss in Sydney

    Sump 4x2x1.5

              Filter socks -> Jap mat -> pot scrubbers -> return 

    Stand: 50x50x4mm steel  900mm high painted with bed liner

    Heater: 2 x jager 300W with an Inkbird controller

    Internal flow: Sunsun wave maker(not sure if I will need this)

    Gravel: 50% crushed coral aragonite 50% Bunnings play sand

    Shells: Marine shells from Shelly Beach, NSW

    Water aging and change: 240lt wheelie bin with small powerhead to get water into tank/sump

    Return pump: Ecotech M1

    Lights: 4 x 3ft cheapo LED with dimmers added by me

    Background: XPS + Styrofoam + expanda foam

              Joined with silicone and skewers and then covered with Crommelins pond sealer and sand

              Stuck to tank with about 20 tubes of silicone



    FISHLIST     I intentionally don’t want anything too expensive or rare.

                        As it’s a very broad mix there may be failures as they grow, pair and breed.

  3. Thanks heaps Chuck. I appreciate the video

    I agree simple is best.

    I think I will alter my design to be more like yours.

    The reason I had 90mm between my bulkheads / baffles was so I can fit my hand between them

    It looks like most people don't worry about that

  4. I am probably over thinking this too much.

    Reviewing my own design I think the wet dry section has to go as it is too hard to get enough bioballs above the waterline

    I know there are other biological medias that don't need to be wet/dry.

    I want to run the filtersocks and have a section where the weir overflow can enter the sump with out splashing (ie pipes underwater) other than that im open.

    Of the various types of filtration what is the best order: Mechanical ->Biological -> Chemical ??

  5. Hi All,

    I would appreciate any help with the design of a new sump I am making for a 7x2.5x2.5 Tanganyikan display tank.

    The sump will be a 4x2x50cm (mixing units sorry) as seen below.

    The tabs that stick out of the vertical pieces in my drawing will hold perforated trickle plates. Some who support media and some who aid dispersion.

    I wanted to use filter socks and have an underwater entry to reduce noise but also want wet/dry section for biological filtration.

    I then redirect the water through a bubble trap/slow down into a section with sponge and carbon through another bubble trap and into return section.

    The bubble traps are large enough to fit my hand down.

    There is loads of spare volume in the sump to take the overflow from the tank if return pump stops.


    What have I missed?
