OziOscar Posted June 15, 2004 Share Posted June 15, 2004 Hi! Just in short I want to know if Sera San is a naughty food (ie hormones, etc) or if it's just like the Hikari colour enhancing products. I've used some Sera products in the past and they have been nice quality, so am considering to add this to increase the variety of diet for some of my livestock. Any knowledge out there? Cheers - OziOscar. Link to comment Share on other sites More sharing options...
j.s Posted June 15, 2004 Share Posted June 15, 2004 I've never used it myself but Sera are quite a reputable brand so i think the food will be fine. Then again i could be wrong...probably best to get the opinion of someone who has used it before. If your females start coloring up like males then you'l know you'v got a problem Link to comment Share on other sites More sharing options...
jaz1986 Posted June 16, 2004 Share Posted June 16, 2004 Any colour enhancing food will affect hormones... cause hormones control colour.... but as was said earlier... sera is a reputable brand... I have used it to no ill effect... and the only ingredients that could be detrimental have been so heavily refined that there should be no harm in them... ie... they should not effect sex hormones...

bob12369 Posted June 16, 2004 Share Posted June 16, 2004 Hi, I use Sera San to feed my fish & the fish love it. The colour difference is really noticable after only a short time, it provides good growth too. I have read a lot of the Sera Guides and the ingredients are only naturally based & extensively researched. But as others have said Sera is a reputable brand & I highly doubt that your fish will suffer i'll effects from feeding this food. Link to comment Share on other sites More sharing options...
graceless Posted June 16, 2004 Share Posted June 16, 2004 don't get angry at me for asking this guys.... but what's wrong with color enhancers anyway? particularly for a display tank? how come hormones (whether natural or synthetic) are give such a bad wrap?

Gav Posted June 16, 2004 Share Posted June 16, 2004 Ozi I use this as my staple flake and it is awesome. Another guy I know has used it for years without a problem. No "naughty" ingredients, just natural colour enhancers. You can pick a 2.2kg bucket for about $120 or so I think. I don't tend to look at the price hth Link to comment Share on other sites More sharing options...
OziOscar Posted June 16, 2004 Author Share Posted June 16, 2004 Everyone: Cheers! I'll try it out on a couple of tanks and look forward to enhanced colour and growth. Graceless: Hormone loaded food is bad because some of them cause females to colour up like males. Some unscrupulous and / or not-too-bright folk could easily sell an F as an M. Not to mention that as soon as hormone treatment stops, colouration return to normal. It's kinda like female body-builders using steroids etc that are more commonly associated with males - there are some pretty nasty side-effects (and in the males too). Also, selling hormone fed fish isn't allowed in the classifieds here and there's a good chance that if a seller is known to be feeding hormone enhanced foods that no one would buy anything from them, for safety's sake. At the top of the technical forum you will find this thread pinned - it's full of interesting info. Cheers - OziOscar. Link to comment Share on other sites More sharing options...
jaz1986 Posted June 16, 2004 Share Posted June 16, 2004 grace- using hormonal colour enhancement foods in a male only display tank... should ba fine... although... once females are involved, there is alot of uncertainty about they effects of hormonal colour enhancing foods... when people say "natural" or "artificial" it basically means derived from krill and spirulina for natural, or derived from capsicums (paprika) for artificial... the "artificial" contains precursers of testosterone... and the spirulina contains phyto-oestrogens... can you really win??? read up as much as you can, don't try to sell hormone food fed fish till well after colour has returned to normal- for your integritys sake... and at this stage... untill more is learned and proven with scientific research methodology, be cautious... if you want to talk to me more about it... off record... feel free to email me at aantreklik(at) optushome.com.au Link to comment Share on other sites More sharing options...
OziOscar Posted June 16, 2004 Author Share Posted June 16, 2004 Jaz1986: Funny... I would have thought that artificial meant 'laboratory produced from chemicals etc' rather than extracted from vegetables / organisms... Do you have a source that I can read about this? I'm very interested to learn more. Cheers - OziOscar. Link to comment Share on other sites More sharing options...
jaz1986 Posted June 16, 2004 Share Posted June 16, 2004 check out most of the websites of the manufacturers... that should tell you the source... the "artificial" part in super G is just that they have been refined in a lab.... they are naturally about 0.5ppt in the fruit... I was reading through a variety of fish culture, aquaculture and fish biology books in badham library at sydney university... i can't remember which one exactly had the details on hormone foods... but its there... I can try to find out which book it was exactly next semester if you want me too... you will have to wait till august when I go back though Link to comment Share on other sites More sharing options...
OziOscar Posted June 16, 2004 Author Share Posted June 16, 2004 jaz1986: Yes, I would love to know what book it is! Something to get the gf to do for me. More knowledge = very good. August? No worries. I've gone 30-something years without the knowledge. A couple of months won't kill me. :D Thanks for helping. Cheers - OziOscar.

jaz1986 Posted June 16, 2004 Share Posted June 16, 2004 pleasure mate... one book you may want to check out... (it doesn't talk much about hormone foods) but it is "Handbook on Ingredients for Aquaculture FEeds" by Joachim W. Hertrampf and Felicitas Piedad-Pascual- published by kluwer academic publishers.... it goes through most major feed ingredients... and talks about their feed value... and will give some pretty good tips on what to use if you ever decide to make your own (i tried my hand at that today... it is a bit of fun, alot of mess) I will be back at uni in the first week of august, so if you pm me around then, I will get the reference for you... Either that or I could photocopy and fax/post it too you Thanks Jared Link to comment Share on other sites More sharing options...
OziOscar Posted June 16, 2004 Author Share Posted June 16, 2004 Thankyou for the heads-up on those... Gf is an ICU nurse at RPA and still enrolled at SU on some other things (never-ending-academic) and has agreed to bring those to me (or copy the useful bits if they are in Stack). This will indeed be interesting!! Let me know anything else that pops up in your travels. Cheers and thanks - OziOscar. Link to comment Share on other sites More sharing options...
