Hello!

I have cause to be concerned, I think.

I have a four foot tank that has a variety of fish such as 5 black-finned silver sharks, a ghost knife, a clown loach, 2 phantom glass catfish, 2 coloured widows, 2 tiger barbs, 3 dalmation lyretail mollies, and 5 guppies, as well as 4 bristlenose catfish to keep it clean.

About two months ago, one of the Tiger Barbs got rather fat for no reason. He stopped being the most active fish in the tank and just hides most of the time. We thought he might have a digestive problem and tried epsom salts but nothing changed (after doing some research though, I am not sure I put enough in). In fact, he's still alive, still gets food during feeding time, but has remained fat. We decided to keep an eye on him, fearing the worst, but he kicks on.

Then very recently, a guppy got fat very suddenly and died, I'd say within two or three days. Then, a second guppy has now gotten fat, doesn't swim around like the other guppies, just sits at the top slowly moving around until its feeding time. He's been like this for about a week or two now. There as about a month or so between the two alive fish (the guppy and barb) getting fat.

Tank size: 200L (4 foot)

pH: 7.1

ammonia: er... need to get back to you on this one
nitrite: and this one
nitrate: and this one. The pet store indicated these seemed normal though.
kH: ah...
gH: not much help am I...

tank temp: I know this one! 29 degrees C

Fish Symptoms (include full description including lesion, color, location, fish behavior): one of the guppies with a flame job on his tail has gotten fat, as well as one of the golden tiger barbs. Neither seem to look much different other than being fat and slow, no fins missing, no unusual scales that I can see.

Volume and Frequency of water changes: I change around 20% every week, maybe one week a month gets skipped.

Chemical Additives or Media in your tank: No chemicals, I have bio noodles and a bio sponge in an VIA Aqua 750 1200l/h canister filter.

Tank inhabitants: 5 black-finned silver sharks, a ghost knife, a clown loach, 2 phantom glass catfish, 2 coloured widows, 2 tiger barbs, 3 dalmation lyretail mollies, and 5 guppies, as well as 4 bristlenose catfish

Recent additions to your tank (living or decoration): The dalmation mollies are a recent addition but both these fish got fat before then.

Exposure to chemicals: None that I am aware of.

Food: I feed the fish tropical flakes and algae discs for the catfish. On the odd occasion I'll put some cucumber or zucchini in for the catfish though all the fish seem to eat it, except the guppies.

Tank Age: 6 months

Recent Events: Addition of mollies but again, this happened before they arrived. Nothing unusual when they got fat. Note that the barb got fat a good month before the guppy did.

Location: Newcastle, NSW, Australia

Digital photo (include if possible): As follows

To be honest, I don't even know how to tell the difference between a male and a female guppy.

Here is the sick one. Sorry if the photos are bad quality, still getting the hang of shooting them properly:

Here is one of the healthy guppies:

The guppy with the flame job on the tail is the sick one, pretty much just slowly cruises around on the surface all day.

The barbs were really hard to get photos of due to low light and them trying to hide so much, but I tried...

In both of the photos, the lower Golden Tiger Barb is the sick one, just fat and generally doesn't do much, but has been living like it for weeks so who knows.

I feel terrible when my fish die, I am keen to sort this out. Please help!
 
What do you feed your fish.
Need more frozen foods and veg in there diet.
Daphnia very good at digesting a fish good.
What does it look like when they go to the toilet.
Are scales sticking out.
Need water stats as it the first thing to rule out.
Take a sample of your water to the lfs and tell them to write the readings down for you.

Cook some frozen peas for a few minutes,. let cool down and pop out of shell, mush between
fingers into small peices and add to the tank.

Epson salt baths help to draw the fluids out.

Thanks for the reply, bit of a delayed reply here. The guppy ended up dying very soon after. I think you're right, the diet is a good place to look.
 
Ok.
Good luck.
 
my albino tiger barbs...which im pretty sure is what you have, would always get real fat during feeding time. they graze all day on small litter in your tank. also the females will have what almost looks like a beer belly. it juts out a little bit below their gills. i have 1 tiger barb that is very fat...but i realized hes the dominate one and gets most of the food.

as for your guppy dying, it could have just been coincidence. if your tiger barb dies then i would worry...but i really think hell be ok.
