    The picture looks more like a retouched North American minnow or something.
    We use a lab diet from a UK company, ZM Systems http://www.zmsystems.co.uk/index.php?app=gbu0&ns=catshow&ref=Fryfood, we find it excellent as a supplement to the live foods we use for fry. Many species accept it eagerly at the different grades.

    If I understand it correctly, that term has only been used where provenance wasn’t available. Assuming due diligence was carried out for ID of those samples (and I doubt it would matter if the Xiphophorus had a bit of mixed blood, for example), I don’t see a problem with it, indeed I think it potentially shows good scientific use of aquarium collections.

    Who is “they”? There seems to be as many ways to maintain a reef aquarium as there are reefkeepers, I know that some specialised methods do involve large amounts of high-grade carbon, but that does sound very expensive and maybe not the simplest way to go about it.

    Switch on the lights at night, look for flatworms on the glass. RCS are usually bulletproof. Added any new plants within recent weeks? Some plant imports are treated with insecticides, that also has a bad effect on anything with a chitinous exoskeleton. Only needs small amounts. I know you say that it’s only the original adults that are dying and so this doesn’t fit, just trying to eliminate a few obvious shrimp issues.
    We have RCS here at temperatures between 70-82F without issue, I’ve housed them outside over a UK Summer when average temperatures were probably around 65F without issue, hard water, soft water, clear water, green water.

    Looking over the tree again, I’d like to hear how this has been received within the field. The Fishbase team must be holding their heads and groaning if this is accepted. There are a number of obvious “eh?” situations.

    Adult Galaxies do hide anyway, they’re little swines for it. Babies bod about in open water, but as soon as they get pretty, they’re gone! We have a display aquarium of 20 gallons or so, there are probably a good several dozen in there, but all you can usually see until feeding time are the half-a-dozen or so juveniles that are growing up in there at any one time. The aquarium is filtered with a sponge filter and a treatment pod with coral gravel just to buffer it slightly, so there is little flow.

    No Orestias annoyingly, or Goodeids, or Anablepidae.
    I’d like to see more work done on this, look how far apart Epiplatys and Aplocheilus are! (I’d always assumed those were all part of an African/Asian radiation where the dessication of the ME, western Asia and eastern Africa had removed evidence apart from fossil taxa like Kenyaichthys)
    Rather messes with easy categories, Certainly the BKA and the AKA etc. must be having identity crises!

    If the filter is as shown in this manual http://www.aquaone.co.uk/documents/AquananoInstructions.pdf, I’d just carefully drill more holes below the slots marked “3” to about 1/2 the depth of the filter unit, and also on the upper area of the right-hand face. This will spread the intake over a larger area, giving gentler flow into the filter.
    You could also look at the outlet, and with some pipe offcuts and a small drill bit you could create a short spray bar to disperse the return flow.

    Excellent book, well worth obtaining.

    You’re in a select club if you’ve had these successfully breed for you.

    Stunning fish! It’s likely IMO that at some point Biotodoma will have more than the two described species. Whether yours represent variation within forms of cupido or are two different species, impossible to say. I’ve had two other forms of cf. cupido from Brazil, love those fish.

    The pyrethrins are only contained within the fruits, so the use of that water may be OK (although it’s possible cut flowers are treated with other nasties during importation to get rid of potential pests).
    The thing to consider is, that particular approach may work for one person who sticks rigidly to a routine, but could very easily be a disaster for others. What he’s doing is using the whole aquarium as a filter, but as has been said, a Hamburg Mat-style filter willl do this far more efficiently and reliably.

    I agree on the Osprey, that was my first thought, only just seen this, need to check my notification settings. Same on the Pipit, although I don’t profess to be able to distinguish LBJs, if it’s by seacliffs I call it a Rock Pipit, inland on grass a Meadow Pipit. Wouldn’t know how to tell either from a Tree Pipit (except for being up a tree, which any of them could be).

    Acnodon are large river fish aren’t they? However, mouth spahe is much more like. Cool!

    (edit) fits with the reported juvenile habitat, so definitely cool!

    Very young Myleus show that kind of pattern, but the mouth doesn’t look right.
