This is getting to be annoying :rolleyes:.

I saw one of the Gobies go after a Danio and it prompted me to take a closer look. And after eating all but 1 of my Neons, 3 of the 6 Pearl Danios I purchased yesterday are gone. The Danios are TWICE the size of the Neons...and 2/3rds the size of the Gobies. At about 1.5" I didn't even consider the possibility that they may be eaten. ****!!

PS...yes, they are doing fine in full FW....PLEASE don't get started on that topic again :cool:.

they may be doing fine now but that's only temporarily, eventually they will get sick and perish. I thought this with BB gobies but again I no longer HAVE BB gobies. You can listen or be ignorant and not listen to my (and others warnings).

Not good at following directions are you?? Two months and not a problem. Just out of curiousity...at what point will you admit that you were wrong...that the fish have not, and will not get sick?? 4 months?? 6 months?? A year?? Or will you endlessly spout your "my way is the only way" crap?? Narrowmindedness = ignorance.

Admins/Mods: if this post is a bit too "straightforward" for this board, please let me know.

They'll be FINE in FW... I've known people who've kept them for YEARS in FW with no ill effects. The only brackish water fish I've never seen do well in FW if careful attention is paid to water would be some species of FW moray eels, and orange flame blue fugu puffers....

Hey, I'm ready to admit that I was wrong...Does my conciliatory tone warrant some pix? :D

Joe, sounds like you need to get some less expensive feeders! :) Let us know if these Gobies start eating something twice their size--sounds like they're well on their way!

My larger gobys (gundgeons) eat anything they can fit into their mouths. They love crickets!

Knight Gobies = Piglets.
The are the biggest pigs in my tank. Trying to out run the mollies for food all the time. :)
As for the Debate on keeping them in Freshwater, I have kept one for about 2 years in a freshwater tank by himself and he was perfectly fine. High weight, high color, and was very active in the tank. The only reason I do not have him anymore was do to the fact i moved and gave him to the LFS.

No one is saying that it can't be done, they are just saying it shouldn't. I don't want to burn burnt bridges but as fishkeepers it is our duty to replicate the natural environment of the fish we keep. That means keeping brackish gobies in brackish, adjusting Monos and Scats to salt when approaching adulthood etc. This is the last post of this type that I will respond to because I am getting kind of fed up lately with people not keeping the fish in the right environment and they wreck havoc on the tank they are in. It is not only you Joe, I am more fed up with the people where I live that return fish on a constant basis where they could no longer care for the fish. Sorry in advance, kinda in a bad mood since school is coming to an end this month and am VERY stressed. But this is the last of this type I will respond to because I feel like I am burning burnt bridges.

Down to two Danios now. If anything, the fact that they are eating everything makes me consider giving them away to a local fishkeeper. That'll **** some people off...but whatever.

I'll get around to posting pics sometime in the next few days.

Of course they eat danios! ;)
That's what I feed mine every month as a treat.
And it won't matter how big they are. I put in a platy who is 10x the size of your average neon and they thought the poor thing was food even though there was NO way he was going to fit into their mouths. Which is funny because they never try to eat the little bumblebee gobies or the smaller platy that lives with them.

I AM AN IDIOT!!!! (<<throwing meat to the wolves :cool: )

No, I haven't rethought my fishkeeping policies :D .....but I've now accounted for all of the Danios.

I'm now back up to 4 living Danios. It seems that they choose to either flitter near the top of the water, or hide in the deepest, darkest, out of the way corners of the tank in some plastic plant thickets. The other two are accounted for....one tried to make a break for it thru a 1"x1" opening in the top and ended up on the floor. The other looked like it got halfway into a gobies mouth and was spit out and died from the experience.

Wow, I missed my chance to say something...that meat still looks good to this Dawg...J/K, Joe.

I'd never heard of Danios being good hiders, but it looks like a few of them might stay with the Gobies and create one of those serendipitous tanks that few pull off b/c they are way outside the rules, but are pretty darn cool-looking.

Pix...PLEEEEEEEEEEEEEEEASE?

Nag nag nag. :D

Here's a pic of the overcrowded tank...(GASP!!! more heresy).

Hey...aren't those all the same fish that have been in there for months??? Don't they look stressed??? :rolleyes:
http://mysite.verizon.net/res0t2li/fish2.jpg

Kinda hard to get a good pic of a shy pleco (must be stressed):
http://mysite.verizon.net/res0t2li/fish3.jpg

The best I could do on short notice. As you can see, I had to enhance the h3ll out of the pic because he wouldn't come out of the shadows. The rest of the gobies are hiding in the fake root/decoration. EDIT: One came out and posed while I was typing this post.
http://mysite.verizon.net/res0t2li/fish5.jpg

The 1st pic was taken a few days ago. The 2nd 3rd an 4th were taken about 15 minutes ago. You can see by the 2nd pic that the Danios have have found each other and don't hide anymore. They stick to the bottom...where they balance the tank nicely. Now they avoid the gobies. :cool:

One of the Danios was almost dinner, but he/she's recovered. And I still have the one Goby with the lack of apetite. It seems that the inside of his mouth is swollen, his jaw seems to be deteriorating and he can't swallow much if any food. I'm doing my best to hang onto him, but I don't think he's gonna make it :(

1.) :D Love to nag, as I love to see that tank!

2.) Isn't that always the way of fish? Never posing for you on time...stubborn little critters!

3.) Glad to hear that the Danio has recovered.

4: Definitely Most Important) If you have a quarantine tank available, I would suggest using it for this fish. There is a good book out there called the "Tropical Fishlopaedia" by Bailey and Burgess which will have info on all types of diseases so that you can diagnose and hopefully treat the fish.

Hope this helps, and thanks for the pix, Joe!

Don't have a quaratine tank. Don't have room. Either way...this doesn't look like a treatable "disease". I don't know if this is possible, but it looks like either it's a genetic thing - the inside if his mouth is growing, while the rest of his body is not so his throat is gradually being restricted - or if he's been injured somehow. This is the one I reported who's mouth was just gaping. The gaping has reduced, and now he does a lot of "yawning". He'll die eventually...but I'll keep trying to feed him soft food anyways.

I hear you, Joe, sometimes there's just the best that we can do, and, after that, there's nothing. Here's hoping that there's a survivor in that tank ready to prove you quite wrong about his chances.

The clamped fins lead me to think that he might be diseased, but they could just be a manifestation of the stress which he is obviously in with that mouth...I'll see what I can find.

joe schmoe
05-11-2003, 11:28 AM
Not clamped. He'll raise them sometimes, it's just without eating much he just doesn't have the energy. Swimming around is tough too. He's a good candidate for euthanasia...but I've never had the balls to do that.

From what I'm finding, some gobies do have their mouths open, but it usually coincides with aggression. I don't think that I can help you any further, and you probably knew that already. Best of luck, and here's hoping for a miracle from the little guy.

He might have dislocated his jaw. It is extremely common in gobies and eels (especially in saltwater- Echnida nebulosa the Snowflake Eel gets it the most often). Sadly most perish because they can not feed. Don't know how to help. Sorry. BTW, I am quite impressed that you have happy healty acidic loving and alkaline loving fish together (Rams and Gobies).

Thanks. I take pride in my work.:p

It may have started as a dislocated jaw, but it seems that the jawbone itself is deteriorating. I just tried some pre-softened flake food and he went for a piece...but it seemed to hurt him to try to eat...he nearly spasmed trying to expell the only flake he tried to eat.

I enhanced this pic to bring out the area in question:

I'm sure there's no remedy...but knowing a definitive cause would be nice...so others can watch for it.

ChilDawg

Two thoughts...Lymphocystis or Vitamin C deficiency...that's all that I could really find in the Fishlopaedia.

That you did. I just hope that the others continue to thrive as they have.

Sorry for the loss.
