Figured I would share my experiences with a recent bout of saprolegnia on a group of Lorenzo tadpoles in a communal grow out. The short story is a tadpole died in a 2.5 G community grow out and I didn't notice. I found it decaying so I removed it, but then I noticed a second tadpole had strange growths on it. Here are images of the second tad that developed the problem:

Overall not a good sign. I immediately pulled the tadpole and checked on the remaining third tadpole that was farther along and it appeared fine [at the time]:

Here's the pulled second tadpole:

After googling around a bit I settled on a saprolegnia infection. I'm not sure of the cause of the original infection which I suspect took the first tad, but from what I have read, it was likely some kind of immunosuppression possibly due to stress. The problem *I think* I was encountering with the second tadpole may be the presence of elevated zoospores in the grow out following the death of the first tadpole. I only had Methylene Blue available that night, so I treated with MB in a cup, and a bit of salt in the original grow out to target any zoospores remaining in the grow out.

Unfortunately the second tadpole was too far gone, and it was dead by morning. I rechecked the remaining third tad that morning and it too was infected. I didn't get a photo of the fungus developing on the third tadpole, but referring back to the original image, I can now see the source:

So that little dot ended up being a full saprolegnia the next morning. I did some reading on treatments and picked up Malachite green (sometimes it goes by Victoria green in pet stores) that day. I treated the grow out tank itself with the prescribed amount of MG that evening. By the next morning, there was no visible sign of the fungus.

All this occurred two weeks prior to this post. The third tadpole has since morphed out and is outwardly healthy. Here it is in the grow out earlier this week:

Here was the article I found helpful on treating saprolegnia:

Hopefully this helps someone else if they ever run into this. It developed very quickly. I keep MB around for treating eggs, but I'll have Malachite green around now in case this happens again. It's probably uncommon for folks using cups, but I use these communal grow outs, so this may be one of the downsides to that rearing method.

I'm also wondering if MG could be helpful in treating eggs for fungus. It was impressive how quickly it worked in this case.

Quote:Venomous animals have toxins associated with delivery mechanisms that can introduce the toxins into another animal [ 1 ]. Although most amphibian species produce or sequester noxious or toxic secretions in the granular glands of the skin to use as antipredator mechanisms [ 2, 3 ], amphibians have been considered poisonous rather than venomous because delivery mechanisms are absent. The skin secretions of two Brazilian hylid frogs (Corythomantis greeningi [ 4 ] and Aparasphenodon brunoi) are more toxic than the venoms of deadly venomous Brazilian pitvipers, genus Bothrops [ 5 ]; C. greeningi secretion is 2-fold and A. brunoi secretion is 25-fold as lethal as Bothrops venom. Like the venoms of other animals, the skin secretions of these frogs show proteolytic and fibrinolytic activity and have hyaluronidase, which is nontoxic and nonproteolytic but promotes diffusion of toxins. These frogs have well-developed delivery mechanisms, utilizing bony spines on the skull that pierce the skin in areas with concentrations of skin glands. C. greeningi has greater development of head spines and enlarged skin glands producing a greater volume of secretion, while A. brunoi has more lethal venom. C. greeningi and A. brunoi have highly toxic skin secretions and an associated delivery mechanism; they are therefore venomous. Because even tiny amounts of these secretions introduced into a wound caused by the head spines could be dangerous, these frogs are capable of using their skin toxins as venoms against would-be predators.

Hi guys,
I am just getting started in the hobby and I am totally hooked ! :oops:
(even tho i don't own a single PDF related thing, except 30+ bookmarks)
This is not how I wanted to do my first post here....
But I would need some advise.

I found a place that makes custom vivs. for a good price. (btw am in Canada)
I wondered if you guys could have a quick look at his pictures and tell me if it would do the job and what i should ask him.

I already asked if it could hold water (1"-2"), if i could have the sliding door on top without any screen and a small hole in the bottom.
He said yes yes no...

Is there any thing else i should inquire about or ask of him.
Maybe more pics of the sliding door ?
I'd really like to start off the right foot.
I asked him for a 36x24x24

If there are other species outside of this genus you can list them too. The one problem I can remember of the tiny species is that they are hard to come by and are expensive.

I'm kind of looking for a challenge. It's the reason I've been cutting back on my collection in the last year. I decided not to buy any new frogs until I can find a more difficult species to work with.

hmmmm....can't say I think this is awesome. Wonder how it reads

I need to drum up some money for MACNA frags. So i have decided to clean out some frog tanks.

I found a monster marcgravia "thing" growing in one particular viv.
asking $15 for a big cutting mass and $10 for a small.


Let me know if you are interested....

Must I feed Fruit flies? Don't they eat all kinds of bugs in the wild?Yes and yes. Wild prey insects of all types have a huge calcium content transferred directly to the dart frog. We can never hope to replicate the diversity of vitamins and nutrients AND calcium they get in the wild, that is why it is imperative that we use fresh, quality superfine supplements as dusted fruit flies at EVERY feeding. Failure to supplement correctly is my guess at the cause of most problems.

Fruit flies must be the staple in the hobby as they are the best possible vehicle to transfer the superfine powdered supplements to the frogs and the easiest to culture. All other feeders - bean beetles, aphids, isopods and springtails are really never able to be well dusted or predictably raised and as such, never a staple feeder insect.
If you want to try crickets as a staple or you feel lazy or unwilling to buy fresh and quality supplements and learn how to properly dust the flies...Then Dart Frogs are not for you. Please try cherry shrimps or some type of goldfish perhaps.

Fly culturing is both the easiest thing as well as the hardest thing about this hobby - you will *get* this odd quote very soon. Fly culturing has some possible off-putting smells and aspects and there will always be escapes. If someone is squeamish about bugs, escapes or possible gross thing, this may not be the hobby.

There is NO SUCH THING AS A BIOACTIVE / SELF-SUFFICENT ENCLOSURE.

There is no way that a tiny glass tank will generate rich and varied insect prey that is nutritionally sufficient for the growth of ANY vertebrate.

A diet of springtails and isopods will not be enough. That's the equivalent of you eating nothing but little debbies and hotdogs (not nearly a perfect analogy but you get the picture, or at least I hope to god you do.

Your frogs and vertebrates will suffer and die unless you give them quality dusted prey items containing the amount of calcium and vitamins that they need. You need to dust with fresh superfine supplements EVERY single feeding.

There is no single competent / long-term frog breeder than does not use melaogaster fruit flies as the staple and dust every feeding.

Nope again, A friend of mine in MD raised generations of HUGE terribilis (google it) on nothing but small melanogaster fruit flies. Will the frogs get bored with nothing but small flies. Nope. That's anthropomorphizing them, a common mistake. We cannot attempt to diversify their diet and it's more mites than ants. I know about 50 of the major breeders of dart frogs in the World hobby since 2005. I don't know of anyone who attempts to feed them any kind of roaches.

So I've been patiently awaiting NEHERP to release their vert kits but its coming down to the nitty gritty. Does anyone have any word on when "anyone" will be releasing an eye pleasing/ clean looking kit anytime soon?

I suppose I could always build one by piecing together items I can find online (not knowing first if they'll work together). But that takes time and most likely more money than what I can purchase a few kits for....

Anyhow, to reiterate. Does anyone know where I can get a nice looking pre-fab kit or know when one of the few companies will be releasing their new creations?

....sure wish junglebox was still in business, I really like the looks of those.....
