[gundamcichlid]

Hi

I have lost couple 4-5cm albino longfin and shortfin with the belly of them is become dark.

there other that left are 1 male 11cm and 3 female 7-8cm and 3 fish 4-5cm

They are in 90L tank, 60x36x 45 m with sponge filter and half liter matrix scatter in the bottom and bare bottom

Water parameter is fine an the adult seem ok and eating

Anyone had experience this before and what might be the cause and the best solution or prevention please share

Panic mode "ON"

Thanks

Dark belly is often from an internal bacterial infection. How often do you scrub the bottom of the tank? Could be a build up of bacterial slime. The fry are more vulnerable simply becasue they are smaller and more fragile.

What should i do to medicate the tank or just scrub and do water change?

Thanks

 

[Lornek8]

Scrub and water change. I am not sure what meds you have available for internal bacteria but that may help as well.

i will try this this afternoon
Cheers

I doubt one sponge filter is enough to support that many of that size fish in a 90L.

Get an eheim 2213 canister on there and probably a nice eheim pickup internal sponge filter as well or at least add another sponge filter to the tank. Get some movement into that water so slime isnt getting trapped on the bottom. With two cycled sponges then at least you could move some of the fry to a new 2ft to grow if you move one sponge out to it later on.

Is there good soft wood for the fry to gnaw on? Sometimes a piece can get just a bit too old and hard for the littlies to get much out of it.

Thanks for the advise

Manage to take picture below

Did 30% water change and scrub the bottom and add more matrix pond to the tank

All the adult seem fine and will get more driftwood this weekend

Cheers

could be some type of infection.
keep water changes going for a few more days.
what do you feed them on?

 

[Lornek8]

Did the belly turn dark before it died or just after?

 

[gundamcichlid]

@Irene0100: I feed them Hikari catfish disc, zuchini, New era catfish and pleco

@Lornek8: I am not sure before or after, I just found them already breathless and took a picture.

Any advise for medication? or just do water change?
thanks in advance

 

[Lornek8]

How often do you feed each food and in what quantities?
Did any of the fry look unusual before they died? Bloating?

 

[gundamcichlid]

i feed twice a day and only feed if i dont see any food left

Used to be 1 m/3 female adult and 8 4cm fry.
i give 5 hikari small disc and a pinch of newera catfish(1/4 tsp)
i feed zuchini every twodays and when feeding zuchini no pellet food given

I did not notice any bloat

WC once a week about 20L

 

[Lornek8]

Seems like a lot of animal proteins to me. Fry can be more sensetive than adults and maybe why you're only seeing problems with fry. Should be more like zucchini everyday and pellets every couple of days.

 

[gundamcichlid]

ok.

I learned from my mistake. Thanks a lot mate!

 

[Irene0100]

I agree, less hikari, try some peas as well (with skin off)
I would water change every day for a few days, 20%
then if any sign of poorly fish try some ESHA 2000 if you can get it as it covers a wide range of illnesses.
