nefastus tooth problems

Oh no! Sick fish?! Come here and see if someone can help!

Since this board has been up, we have found there are several questions that routinely get asked in order to help diagnose problems. If you can have that information to begin with in your post, we'll be able to help right away (if we can!) without having to wait for you to post the info we need.

1) Your water parameters - pH, Ammonia, Nitrite, Nitrates and salinity (if appropriate). This is by far the most important information you can provide! Do not answer this with "Fine" "Perfect" "ok", that tells us nothing. We need hard numbers.

2) Tank size and a list of ALL inhabitants. Include algae eaters, plecos, everything. We need to know what you have and how big the tank is.

3) Feeding, water change schedule and a list of all products you are using or have added to the tank (examples: Cycle, Amquel, salt, etc)

4) What changes you've made in the tank in the last week or so. Sometimes its the little things that make all the difference.

5) How long the aquarium has been set up, and how did you cycle it? If you don't know what cycling is read this: Fishless Cycling Article and familiarize yourself with all the information. Yes. All of it.

We want to help, and providing this information will go a LONG way to getting a diagnosis and hopeful cure that much faster.

While you wait for assistance:
One of the easiest and best ways to help your fish feel better is clean water! If you are already on a regular water change schedule (50% weekly is recommended) a good step to making your fish more comfortable while waiting for diagnosis/suggestions is to do a large water change immediately. Feel free to repeat daily or as often as you can, clean water is always a good thing! Use of Amquel or Prime as a dechlor may help with any ammonia or nitrite issues, and is highly recommended.

Note - if you do not normally do large water changes, doing a sudden, large water change could shock your fish by suddenly changing their established water chemistry. Clean water is still your first goal, so in this case, do several smaller (10%) water changes over the next day or two before starting any large ones.

nefastus tooth problems

Post by messy_da_legend »

I've got a couple of A. nefastus, and they don't take any interest in shelled foods like small snails etc. I've been feeding them prawns, bloodworms, a little bit of frozen fish and chopped cockles as they eat that. As you might imagine, they need their teeth trimming because they're not taking the hard foods and they're struggling to eat (getting skinny).

I sudated one with clove oil a few minutes ago to take a better look, and as they're only 1" long I can't see how I'm going to be able to trim them. I can't even fit the nail scissors in their mouths. Any suggestions would be brilliant.

cheers,

Tom

Cuttlefish bone perhaps, put it in the tank and see if they attack it or try and get food attached to it in some way so there is a chance they get some teeth scraping on it. Any joy with cockle in shell tooth wear would be minimal but every little would help especially if you scooped most of the food out so they were picking the bits off the shell.

There are photos of my trimming puffer's teeth that were <1" in our Library. You can do it!

I question the ID of your puffers though. I'd be more inclined to think they were silus or modestus, as I've never heard of nefastus eever being made available in the aquarium trade.

It was posted up that these had become available in the trade from one of the more reputable specialist fish shops in the UK.

Darn, again you guys get the rare stuff over there! I would still like to see the fish for ID & know how it was positively IDed as such.

Cheers for the tips Hilly. Pufferpunk, I managed with my old GSP after reading your article, but once I'd knocked one of these out I got it in the net and thought "how the hell am I supposed to open it's mouth wide enough without hurting it??" :? I will try to trim again and will feed them on bloodworms for now as they're easier to eat. I'll will get a cuttle bone too and see how that works.

After seeing Neale Monks' post (I think it was him) about nefastus at Wildwoods I went down and got a pair. Never got a positive ID so far though. Will have to get some pictures.

Thanks a lot,

Tom

Nice pics Tom

They do look like the pics of the Nefastus on P. 43 of the Aqualog. Silus look a lot more plumper and these are more streamlined.

I'd say they were Nefastus from comparison pics in the Aqualog.

LOL, the 2 silus on the top of page 44, look like totally different fish, so there has to be some other way to tell the difference between the species, than streamlined figures.

Well not many people can get shots of fin rays to count em. So going on a visual comparison they look different to me to silus/modestus.

Which fin do you count? Is it the dorsal? If so, how many should the nefastus have? I reckon if I use the original size image I could count.
Cheers guys,

Silus have between 23-28 rays on the dorsal and nefastus has between 23-27. All the 5 Auriglobus species are extremely close so I dont think it's gonna help you much here.

This is the description:
A Nefastus, uniform pale green or yellow green with light flanks with a darker spot on the upper surface of the head posterior to the eyes. THe protrusion of the upper lip over the lower is characteristic. Spines are downward pointing. Nasal organ is relatively small compared to others apart from A. Amabilis.
