    Looks awesome! Get some other African fish, Polypterus!

    Believe me you won't regret it! You could get 10 or more Senegalus in there haha :p


    There's many options for a tank like this fishwise, choose what you love and you'll love the tank :)

    Plastic World in Selby stocks eggcrate, last time I bought (a while back) it was around R200/ sheet 120cmx60cm, it's actually a light diffuser typically used with neon light fittings in office building, made of rigid styrene, so it's somewhat brittle. Electrical wholesalers may stock it as well.
    Think about what you want to stock before adding Polypterus, they deserve the moniker "dinosaur eels" and may grab anything that's close. As Hendre mentioned, they are cool fish. I have a number of them, the biggest about 45cm.

    Senegals are cool! Staying smaller around 25-30cm and being very chilled, I think @Jwh keeps lower jaw polypterus which are larger and have bigger mouths/appetites. Upper jaw species such as Senegalus, delhezi and palmas species are more community friendly and do well with an assortment of tankmates :)

    I keep both upper and lower jaw polys.
    They are an interesting group. They go well with my silver dollars and other oddballs.

    When you start a new tank there are so many opportunities

    Ok tank installation going to be delayed:(. Family want to go spend the weekend at the coast and I guess kids trump dad.... anyway next question when installing the sump return is it better to have it on the opposite side to the overflow or on the same side pointing as to create the tank to swirl. .. I was planning on two returns one on the surface to create ripples etc and one about half way down to get the deeper water moving, what your guys thoughts on this? Also these wave makers are they any good and what do they cost?

    I would place opposite side of overflow, creates surface flow and agitation. My returns are generally just below surface to keep things silent. Not sure I would place a return halfway down, will reduce flow and may negatively affect your filtration.
    Wave makers are great, can cost anything from R200 to R7000+ depending what you get

    Don't put you're return pype half way down.If load shedding comes to visit or youre power head fails for some reason while nobody is home the water will be sucked back to you're sump to the hight level of youre return pype causing you're sump to overflow and a huge mess.

    Thanks Christiaan, I had considered this this is why I was splitting the return on surface and one deeper, the surface one would hopefully break the vacuum. I am concerned that with this size tank and depth that surface return will not be sufficient to flow near the bottom of the tank?

    Use wave makers or a powerhead with a spraybar to create more flow.

    @RobK .. remember your sump is not a closed circuit like a canister filter... as has been said..you cant put the return at the bottom as you will pick up problems

    I have two wave-makers in my tank and that together with the sump return gives me enough flow on 3200l of water and 4 very,very messy stingrays
    The trick is to watch your tank carefully once its set up and determine where you need the wave makers placed
    Sometimes you land up moving them around two or three times until you happy with the flow
    A decent wave maker (depending on size) should cost you around... R400.00

    Pardon my quick drawn pic but it's just to give you a idea.

    For you're size tank I would look at something like this
    20180114_134807.jpg
    depending on what you going to be doing with you're tank.Maybe a 6000-8000l/h should be perfect?

    Thanks guys, can you adjust the flow on the wave makers? And what would be the easiest way to check your flow? And would it be it hurt to split the return have one as per your drawing ie pointing down and the other with a flow control to "ripple" the surface.. I quite like that effect.

    @RobKMy apologies I could of drawn something to indicate a elbow on the return.I glued a 90° elbow on the return to point the water in the direction I want wich helps with flow direction.The force of the return powerhead will blast you're sand away causing a bare spot if it's pointed straight down. Yes you can split it or you can add a spray bar.

    There is a flow rating on the wavemaker...
    This 1 is a 12000l/h

    I've never had a wavemaker that controls the flow so i cant really say much but I'm sure there are wavemakers with electronic controllers but it will probably come at some cost.
