Picky Cories..

[Seed_Lord]

would recommend 6+, i have a group of 20 in my main set up Mine go crazy for anything, maybe they where fed on a certain food so need a bit of time to get used to what your feeding them? had that with betta's before. Try some frozen brineshrimp, mine always enjoy that, but i've fed mine anything from flake to frozen food to beef heart to discus pellets (yes i have discus in same tank ) and they look equally interested in all of it

I still haven't seen them eat anything.. But I tried an algae wafer yesterday and it seems to have disappeared! There's quite a lot of plants and such though so it's possible I'm just not seeing it. Next I think I'll try the bloodworm idea. And no, they're not on sand, just fine gravel. I think I might have some black sand left over from my other tank though so I could set up a little sand area if I need to.

I also just added three more to the tank so maybe that will make them more comfortable. I'll probably add another couple at some point in the next few weeks after I see how these new ones do.

also notice that they are a lot more active at night time..so disapperance of water is a positive sign..I never see my corys eat neither..but waters always disappears and they seems healthy to me...very active at night...

This could be the problem as Corys shift through sand for food, this is why they can eat pellets even after they fall apart. It is definitely worth adding sand, and if you can't add it immediately, try adding a small plate or tub with sand on it, for the moment.

 

[hannah12]

Ohh.. Maybe that explains why mine don't swim around on the bottom? Maybe they don't like the gravel. And that could be why they're always fighting to sit on top of the magnet--it has a smooth surface which they must prefer to the gravel... I'll try a little plate of sand with some food on it asap.

There are some Corys (mostly dwarfs) which are more of mid-water schoolers than "bottom fish", but in my experience, C. trilineatus are one of the bottom fish. I used to keep them on a mix of 30% smooth gravel with 70% play sand; they spent most of the time sifting, looking for food.

 

[hannah12]

So I added a little dish of sand with a wafer on it, and the algae wafer disintegrated and formed a layer over the sand. A couple of the new cories have been sifting through it, but still no interest from the old cories. It could just be paranoia but I'm starting to think their stomachs are looking a little sunken in. They're rejecting EVERYTHING though, so I'm not sure what more I should do!

 

[KittyKat]

Maybe they're too shy with you around? Have you tried sitting very still on the other side of the room and watching when feeding them after dark?

 

[Seed_Lord]

can always get sand and mix it with the gravel, looks good imo depending on the gravel obv, what ive done in my tank. I use argos play sand cheap as chips looks better than any sand ive seen in a lfs

 

[Ant_Soton]

My Cories eat almost anything, they never stop eating !!!

 

[Rickzayne]

my corys eat during the day when I put frozen blood worms in.

then go through all the sand at night to see if they can find more.

they also like to eat cucumber once its been in for a day and softened up a bit xD

 

[Harlequins]

What food have you tried them with so far?

Mine adore tetramin prima granules/mini granules amongst many other things

I have a few corys that aren't overly bothered with algae wafers,but will eat anything else.

It might be better asking the lfs what they were feeding them on before you bought them

 

[hannah12]

I found one dead this morning, one of the new ones. They all looked fine last night, except for seeming a bit antisocial. The other ones all looked great, so I just took it out and did a gravel vac and water change. But when I was done, I looked for all the fish again and noticed one had swam up to the top and was sitting in a floating plant right at the surface. It looks healthy, except seems to be breathing faster than the others.. Any thoughts?

 

[KittyKat]

How tall is the tank? Do you have good surface movement?

How are the water parameters in the tank? And tap water after dechlorinating?

 

[hannah12]

I use well water, so there's no chlorine in it. Ammonia is zero, temperature is 76 F, pH is 7.6, and there's a Bio-Wheel filter and an airstone. The tank is a standard 29 gallon, and I think it's about 18 inches tall, 12 deep, 36 across. Two of the fish are now completely missing, but the other two (the original ones) are doing fine as far as I can tell. I want to keep experimenting with food but I'm worried if the two other fish have died and are rotting I already have too much pollution to deal with as is. I've been looking for bodies but haven't seen any.
