Electric yellows with concave stomachs

Recommended Posts

hi guys, this new forum is quite spiffy. I have 5 E yellows, a big male 13cm+, 3 7-8cm females and another that is around 12cm that I am unsure of the sex. two of the small girls and the 12cm one have fairly concave stomachs. They are otherwise fine, they are eating etc. I don't want them to take a mouthful in this condition cos they will surely perish? I am feeding: HBH graze flake food "super vege blend", HBH soft and moist spirulina pellets "breeding conditioner", dried brine shrimp, and I have thrown in the occasional crushed up high protien pellet. I also feed little bits of brocoli, califlower and I have put in some zuccini wieghed down with rocks. (come to think of it these little fellas eat better than me!!). what causes this and should i be worried?

also the big male lab has never been observed to eat, I have had him for about 2 1/2 weeks, he never is interested in eating the food I add. all the other fish gather like starving dogs at the top of the tank, but this guy sticks to his cave.

any help on both points very appreciated.

Hi,

Sounds to me like they need worming. Are they also 'caving in' around the head region? If they are eating and not gaining weight, it's usually a sign of worms - prob. tape worm.

Hi,

Sounds like it could be both. I'm not sure about using two products in conjuntio with each other - you may have to treat one then the other. Are any of the other fish showing similar signs? Is this fish newly acquired?

Hi guys,

Gill fluke can often be a hidden infection in that the fish may show few symptoms and handle a few of the flukes just fine. If they do get a bit stressed though (eg with poor water conditions or maybe when they are holding a mouthful) they may not be able to cope as well and often show the symptoms you are describing.

I find fish tend to want to eat, but then 'spit' out the food after. They get skinny, and most of the time (not always) 'flick' themselves against things.

Praziquantel is the drug of choice and is the one used in many fluke and tapeworm meds. It is very safe and very effective. An older cure is formaldehyde in a variety of combinations but that is a much more dangerous med to use. Look for the med with praziquantel as the only ingredient. Some recommend dosing once first day, and then another dose 4-5 days later to take care of any flukes hatching out.

If you have large volumes of water potassium permanganate can be a very cheap and useful tool against flukes as well as many external infections. Koi keepers use this extensively, but you need to keep the dose in the water between 2-8ppm and make sure that you have plenty of aeration. Good thing is that you can reverse permanganate immediately in the event of overdose or adverse reaction using peroxide. Anyway this is a more difficult treatment only practical if you have large volumes of water to treat. In addition this will kill your filter bacteria whereas praziquantel will not.

Another possible internal infection is camallanus. Fish infected with these livebearing worms can sometimes show the worms sticking out of their anus like little red pin heads. Other times you may not be able to see the worms at all. You can treat camallanus easily with levamisole HCl 14g/l at 1ml/7l . Buy it from farm supply stores - just tell them you are after levamisole, pig and poultry wormer.. :8

Hope that helps, praziquantel and levamisole are two very safe meds that are also very effective and specific, and will not harm your filtration.
