Can you tell an eel buy its colour?

With the flood waters in Rockhampton quickly receding I finally got back into my normal place of work along side the mighty Fitzroy river, and saw literally thouands of fish all gasping along the edges of the fast flowing water.

Aside from the thousands of tiny salmon tailed catfish bubs and their monster parents, huge boney bream, sooty grunter, golden perch, long toms, various other small bait fish there was also some monster eels. Most of the eels I saw where the speckled type like this guy

But I also saw some all grey eels (even bigger that rivelled the huge catfish for head size) with a darker strip down their back.

But the most stunning eel I saw was a real bright fluro green, it was really pretty and still fairly lively so alas I missed out on getting a picture of it before it disappeared into the murk again. Are all these eels likely to be the same species/ type just from different sections of our huge catchment or was I seeing 3 definant different breeds of eel?

We have a number of species in North QLD and most are Anguilla species, the grey/ silver one was most likely A. obscura although it is not suppose to be That far South? and A. australis is not suppose to get that far North?. The one in the photo is for sure Reinharti.

I don't think any one has done any serious work on Anguilla sp. in Queensland as a whole.

There was a new Anguilla found up here last year.

Thanks, I knew the speckled guy was a fairly common one, I have seen them plenty of times, but the huge grey type I have never seen before. And the stunning fluro green was a real surprise.

How far south should A. obscura be? Rocky's catchment extends all the way to inland from Mackay or is that still too far south?

I will be back at the river today so I am going to keep my eyes peeled for another fluro green and hopefully I will get a picture of it.

The real sad thing to see with the flood is all the fish dying, amazing and interesting to see all the species but still so sad.

These couple of pictures might give you a better idea how big some of these eels are, although I have seen bigger ones again than the one in the photos

And the sad thing to see, every bay or sheltered part of the raging river has got hundreds of fish jammed into it dying. In this picture there is mostly salmon tailed catfish

but you might also be able to see the sooty grunter and one of the big boney bream

The Wholesalers in Brisbane and Melbourne will take all the Salmon tail cat baby's you can catch!

Must be the vegetation in the river causing the low oxygen? or is the bottom of the river polluted?

OH boy is that going to stink in a few days

It's sad to see so many fish dieing slowly like this. You would think that a flood would help clean out the system and revitalise it, not clean out all living creatures.

Should re home them but running the risk of bringing home a desease probably isn't a good idea.

yes actually....can anyone please explain why they are dying? i'm a little confused and lacking knowledge

They are dieing partly because they have hit salt water, all be it diluted by the fresh flood water. But also from the silt inthe water clogging up their gills and the rotting vegetation. There could also be pollution from the mines and goodness knows what from septic tanks and sewerage.

      Hello folks,  The current problem I am having is that my Taiwan bee shrimp are molting before all their eggs have hatched.  Often the shrimp keep the eggs for 40+ days.  During that time, they lose about half or so, either due to dropping or duds or whatever.  Shortly before molting they look to have about a dozen left, and then they molt with about half a dozen eggs still on the shell.  Then the other shirmp will come and eat the shell.  These last few times, I have been getting around 0-3 surviving babies per batch.  I figure I can make the eggs hatch faster by raising the water temperature more (currently around 68F, which is already a few degrees higher than I used to keep it) or make the shrimp grow slower by feeding them less (protein).  Currently I feed Shrimp King complete every other day, and also a small dab of Shrimp Fit alternating days.  Maybe I can start alternating with more vegetable food like mulberry?  or just decrease the amount of food?

      Yeah, cancer risk was a thing I'd seen mentioned a lot when looking into gentian violet briefly. I kinda just figured it might only be as bad as the cancer risk of malachite green as well, but maybe I should look into it more. I've been doing a pretty good job of not getting it on my skin and also avoiding dunking my unprotected hands into the tank water while treating my fish at least, though. Maybe I'll just not use it once I'm done this course of medication anyways, because I know a store I can sometimes get to that's pretty distant carries both malachite green and methylene blue, and in pretty large quantities.

      Can't help you with Gentian Violet, sorry. It is banned in Australia violet for potential toxicity, and even possible cancer risks. I thought it was banned in Canada as well. At least, you now know why there isn't much info on gentian violet medication and it's use. But keep an eye on the snails after a week. If it affects the snails, it might not kill them immediately. So keep checking for up to a week. Much safer options out there. No point risking your own life over unsafe products.

      Hello! I have a tank that currently does not contain shrimp, but does contain neon tetras which I am currently treating for Ich, as well as some bladder snails. Shrimp will be a later addition, likely cherry shrimp but I'm still doing research just to be sure. Initially I'd intended to buy some sort of Ich-fighting product that contains malachite green after doing a decent bit of research on it, most of which indicated that it should be shrimp-safe so I'd be good if I ever needed to use it again once shrimp were actually introduced (though I should note I'm aware shrimp can't get Ich, I'm more wondering in case the tetras could get Ich again, or something else that responds to similar medication). I ended up not being able to find any MG-containing products without either having to travel quite far or wait multiple days for delivery (which I was worried could lead the Ich to be fatal), and ended up picking up 'Top Fin Ick Remedy', a product that contains gentian violet which is a triarylmethane dye like malachite green. The bottle has two slightly differently worded warnings about its use with invertebrates ("not recommended for" and "not safe for" respectively), but when I'd been researching malachite green, I'd also heard of products that contain MG but not any other ingredients that would be harmful to inverts still being branded with warnings that they could be harmful, just as a "just-in-case" since the manufacturer didn't test it on any inverts, and I'm wondering if maybe it could be a similar situation here. I'm having a very very hard time finding information about gentian violet's use in fishkeeping at all though, it seems currently extremely uncommon. What I will say though is that I'm on day 2 of treating my tetras with it, and the bladder snails seem just fine -- in fact today I noticed what looked to be a bladder snail that appeared to be newly hatched (because of its size) that I hadn't seen before that was zipping around the tank without issue. But obviously, shrimp are not snails, and bladder snails are also notoriously hardy little guys, so what I'm seeing right now could easily be totally inapplicable to cherry shrimp. It might even be inapplicable to other species of snails, for all I know. Has anyone else here ever used anything that contains gentian violet in a tank that actually does contain shrimp? Were they okay, or should I make sure to not use it once shrimp are added?
