hi everyone,

just finished cleaning and water change and found my second b/n dead 3-4 days after the other.

any help would be appriciated, my vitals are :

4ft 65g
0 amonia
0 nitrite
0 nitrate
13kh
12gh
8.2 ph
temp 26c

i was wondering if they were getting enough to eat, i throw in a algae wafer pobably once a week and they get what ever reaches the bottom.
also iv'e been having brown algae problems the last couple of weeks so i'm increasing the time the light is on.

thanks guys

Were they getting harassed by other fish?

How long have they been in the tank?

Throw in some blanched Zuccinni every week, they would be sure to get some of that.

 

[chromedome]

as far as i know they weren't being harassed.

they had been in the tank from the start in january this year.

0 nitrate? Do you know magic? Not even my heavily planted tanks have 0 nitrate.

 

[chromedome]

:lol: :lol: as far as my test kit goes thats what it reads before 50 per cent weekly water changes.

 

[Mitch101]

How long has the tank been setup? Your readings dont make sence. Test kit might be bad.

 

[chromedome]

tank has been running since jan this year

 

[under_control]

Then my guess is bad test kit. What kind of test kit do you have?

 

[chromedome]

my test kits are sera for all readings except ph which i use my swimming pool test kit.

the sera kits are the liquid drops type with colour chart.
the next colour up from 0 is 10 but there appears to be no dicernable difference from the 0 colour when i do my nitrate test.

i did do a test on someone's tank about 3 months ago with this kit and it showed a reading of 50 so i thought the kit was good.

also on the bottom of the box there is stamped 02/2012 so i took it this was the useby.

thanks :?

Do you shake the bottles, as directions describe?

yes :?

Chromedome has done nitrate tests for me on my tanks, and they always come up with a reading. Not fualty guys and he isn't stupid either.
I reckon it's got something to do with the algea that is growing. Most fish stay away from that kind of algae but maybe the BN's were exposed to it a little to much.
Thats the only thing i can think of. They shouldn't have starved they eat all types of things. I don't feed mine at all and he is going fine. He will be devo to find out his X-girlfriend dead but

 

[DJRansome]

I'd be worried about having no nitrate because healthy bacteria generate nitrate. Try not changing your water until you get a reading. It's not planted, right?

Regarding the bristlenose, were their bellies plump when you found the bodies? If yes, then it was not starvation. I've read advice to check their bellies to be sure they are not concave both at purchase and ongoing.

Was there damage to the bodies when you found them? How long were they in the tank with the cichlids? Mbuna are famous for picking on them, especially when they are first added to a mature tank.

I bought 4 and lost 3 initially, but my one remaining BN seems to be OK in a tank of 40 mbuna and 11 catfish for now.

 

[chromedome]

no it's not planted, am i overdoing the water changes?

the first B/N i din't take a good look at before disposal, the second was somewhat eaten.

they were in the tank from the start, after cycling, when the first species of mbuna was added, back in jan this year.

 

[cichlidaholic]

Try shaking the reagent for the nitrate a bit longer, sometimes that can be a factor in the readings you get.

Also, if the test kits have been open longer than 6 months, that could be your problem, as well.

I don't think it's your water with those water changes, though, and I wouldn't change anything about them.

Are you using a good dechlorinator with the water changes - one that removes both chlorine and chloramines?

How big were the plecos?

If it were aggression, I would think it would have happened earlier, and you'd definitely be able to tell by the body of the pleco, especially the finnage.

Are you adding anything unusual to buffer the tank?

my dechlor says : chlorine, chloramine, amonia and heavy metals neutralizer plus slim coat.

How big were the plecos?

one was about 2in the other slightly larger about 2.25-2.5 ins

i'm using non-iodised table salt, epsom salt and baking soda.

[cichlidaholic]

Sounds like you're using the buffer recipe from the library? If you're following that, I've never had a problem using it in tanks with plecos.

I was afraid you might be using one of those ph enhancers they sell at the LFS, that is why I asked.

It doesn't really make any sense, unless it really is aggression related, but that's just never been a problem for me in my tanks, and I've even accidently transfered 1/2 inch baby BN with my net into full size adult tanks without any problems (other than me almost fainting when I saw the little one swimming around in there ).

The only other thing I can think of is that something may have happened to them before you got them that shortened their life span. When they are young, they are super sensitive to water changes, I lost alot of them before I realized I couldn't do as many water changes as I normally do on fry grow out tanks. But, should you go to the opposite extreme and raise them in very dirty conditions, you could do damage to their internal organs that would take awhile to manifest.

Did they both come from the same source? Same tank at the LFS at the same time?

Absolutely no sign of torn fins prior to the deaths?

 

[chromedome]

hi cichlidaholic,

hey thanks for following up on my post.

yes if the buffer recipe is good enough for you guys, yep i'm on board, and no iv'e never used any other form of buffering.

of course i can't rule out aggression although iv'e not seen any toward the plecos but they were awol a lot of the time.

no they didn't come from the same source. one was from an lfs and another slightly older and bigger was from my future son inlaws tank.
iv'e tried by reading this site to keep my water at optimum, although my nitrate readings have become an issue since this post.
i will borrow another nitrate test kit over the weekend and see what that reads.

is it possible i killed them with kindness? or more likely iv'e got a lot to learn!

as for torn fins, well the truth is i didn't notice any. but i wasn't particularly looking for it either, just the darn what have i done wrong as i sent them to fishy heaven.

as mentioned at the start of this post iv'e been having a brown algae problem the last 2-3 weeks
is there any corolation here, as iv'e heard they don't like it but seen them going at the rocks.

sorry for the long reply

Usually they just won't eat the brown algae, I've never seen it be a problem that would lead to death with them.

Since they both came from different sources, that kind of blows my theory on earlier damage being done to them.

I'm at a loss. :-?

the rest of my tank inhabitants seem to be doing fine, so perhaps it was down to aggression.
iv'e noticed my maingano male and sometimes a cobalt blue digging under rocks down to the glass and getting stroppy with the rest, perhaps the plecos got in the way, although iv'e not witnessed it.

if that was the case how would i get on re-introducing new b/ns to the tank? :-?
