Discus not eating / white poo

[BGK2]

Hi Guys,

I've just purchased 5 new Blue Diamond Discus.

3 of them 5days ago (Sunday), 2 of them 3days ago (Tuesday).

1 of them about 8cm

3 of them about 6cm

1 of them about 4cm

Now the larger 4 discus are coming out and eating.

However the smallest discus (bought on Sunday) always hides, and isn't eating.

I feed them frozen bloodworms and tetra bits (that's what the previous owner says they feed it) - I will attempt to make my own beefheart mix next week.

Should I be worried? he sometimes seems interested when I feed them, but will then decide to turn around and hide again.

I've seen the bigger 4 discus poo, and they are not white, but it's been hard to see the smaller discus poo since he/she always hides.

 

My water parameters are as follow:

Temperature: 29C

pH 7.0 (I have used peat moss to lower this, it use to be about 7.4)

Nitrite 0

Ammonia 0

Nitrate 5-10

I do about 15-20% water changes about 4x a week

 

My tank is a 4ft, 55gallon

Current fishes:

5 Discus

3 otos

5 rummy nose tetras

3 german blue rams

 

My tank is planted with driftwood, with LED lights / 1T8

1x Eheim Professional 2222 filter

1x Aqua One Aquis 700 filter

1x Blue Planet 24w UV filter

 

I'll try and provide photos tonight.

I've heard that it is normal for new discus to not eat in the first week or so, but since the other 4 discus are coming out and eating, I just assume that the smaller one will follow?

But I mean, the other 4 discus only started eating yesterday, before that only 1 of them ate.

Ok an update,

Looks like the small discus has white poo (not clear but white).

The colour of the discus is pretty dark.

What kind of treatment should I use? And should i transfer him to a quarantine tank before starting treatment? (or will the whole tank require treatment?)

The other 4 discus are still eating happily.
