Why my arrowanas not eating?

Dear All,

I am keeping 4 pieces of RTG arowanas in a 5 x 2.5 x 2.5 feet tank.
They are 15 months old now and from the same parents. All these months thyy are eating very well (20 - 30 medium size worms a day). I bought them 6months old.

The past 2-3 weeks, they are eating very little (3 - 5 worms) or not eating at all.
I always changing 20% of water (biweekly) and clean the pump (Biweekly too). They are very active and swimming normally.

What happen to them? Please advice? Many Thanks!

What's your ph? Got coral chips in your tank?

4 pieces of 15month old RTG in a 5ft tank and wc is only 20% bi weekly?

Maybe you can consider to change more water and clean wool at a more freq period?

Hey Bros,

Thank you for your reply.
I have some corals in the external ehem pump. How can I measure the PH?

Swordfish

I did check the filters and they are quite clean.
However, the corals already more than 6 months.

Thank you for your time and attention over my worries.

how to measure? get a test kit if u on a budget.
if no budget get a ph meter to live monitor.

biweekly 20%? so little?
i weekly 40% in my 522 leh and i only have 1x 12" aro and a few tank mates

if my ph went too low. i will do a 30% to buff up a bit.

Sick of SW , try change the diet.

For my 522 tank I don't do WC. Instead top up water, if PH lower than 5 then I change 30%. I do not use coral chips , purely on bio ceramic rings. Double wool on each compartment on OHF. Bro, maybe temp. too low, appetite may drop. Just share share.

Imho TS, I suggest u shd try more frequent wc. 20% biweekly wc may not be ideal. I'm keeping 7 pcs aro in my 522, I wc abt 30% every 2 days. They eat like no tmr.
