Perhaps the more virulent strains were not around or well-known back then. I have hard alkaline water and so does Diana.

I believe that they are a separate species. There are just too many differences. They don't hybridize in the wild. They have different gonopodial structures and the courting behavior is different. Pure Endler's also do not jump - guppies do. When they do hybridize, you get an amplifying of phenotypes of the parents rather than something in between. I'm sure there's much more but it all points to speciation. There are probably fewer differences between species of mollies, which can also produce fertile hybrids.

Has anyone had a platy die with a bloated stomach? I notice she was constipated a few days before death. Thus believe death was due to eating wrong food. Two possible wrong foods are dried plankton and shrimp pelets. Anybody had fish die a few days after noticing constipation?

People may be interested to know that there is being developed a new DNA test for ornamental fish suppliers to test for over 60 different bacteria, viruses and parasites in a fish shipment that only takes 1.5 days to do.

Sounds like this will force fish farms to be more healthy and supply us with better stock!

Hey, that is good news!

Hi - I'm new to this forum - was referred here by Diana. I have a question regarding the eradication of pathogens (bacteria, etc) using a UV sterliser. For a 72L tank, would a 9W UV sterliser be good enough? I'm really uncertain and the lowest wattage I can find on ebay is 9W.

David.

dwalstad might know for she uses 1.

Hi - sorry to link to your article Diana - I see that you used an 8 Watt UV lamp. I've ordered a 9 Watt UV lamp - the Submariner model from ebay. Should arrive tomorrow and I'll sort out my 16 US Gallon tank.

Sorry to double post but I can't edit my last post. I didn't have time earlier to carry out a search on the NPT forum on UV sterilizers but now I've seen the thread below from Diana:
http://www.aquaticplantcentral.com/f...-diseases.html Might be good to have this as a sticky too as it's quite important. It's a mine field out there for new hobbyists and a lot of cheap chinese uv sterlizers are on sale that aren't flow adjustable.

Hi All

Can somebody give me some ideas about how you would deal with biofilms with MB on the surface water? I'm going to set up a UV sterilizer to help cycle and clean the water of MB and such but what of the MB in the biofilm? Would you use protein skimmers or just paper towel to mop up the biofilms?

I've posted a new thread asking the same question here - http://www.aquaticplantcentral.com/f...tml#post480831

I was going to start a new thread and found this link. I just had a couple of fish show signs of bacterial hemoragic septisemia (I'm pretty sure I just mispelled that) and ordered some oxytetracycline from fishfarmacy.com after counseling with one of their reps. So far I have lost one, another is looking really bad, and now three others are showing symptoms (reddening of the fins et cetera). I'm new to this disease, and am sadly impressed with how quickly it can spread once established. This also has a lot to do with water quality, as I have a relatively new setup and have been in and out of the substrate with new plants et cetera, fighting the ich that rode in on the back of another fish and stressing the fish out in general.

So as a word of caution, take things slow and don't get in a hurry. For newcomers, GET A QUARANTINE TANK!!! Otherwise you may just end up with the same mess. It's an ugly affliction and I hope no one else is having to deal with it.
