bro usually how long does aro scale need to grow back?

Very subjective question...

Likely to depends on your aro..could be 2 weeks..could be a month..

Coloration to return could take from 1 month to 6 month..depending on diet, tanning, environment, water quality, and your fish health..

Hi, Im a super high bank [4inch] owner (newbie). Can I ask, what's arowana main food ? My aro 4days dun wan to eat already. The first day I bought back it ate 4 birdworms, then 2nd day till 4th day it dun wan eat anything. I put cricket in, it chew 3second then blow back out, it ignored birdworms. Any idea ?

When arowana dont want to eat. Usually is this few problem.

1. Water.
- high ammonia , high nitrite or high nitrate. Usually new tank when bio filter is newly establish.

2. Temp.
- Too cold or too hot will reduce appetite . maintain 27c to 28c.

3. new tank syndrome.
- still not stable due to transport or new tank.

4. food.
- not used to new food or smell from different source even same type of food. mealworm or superworm from shop to shop will smell different.

See reply from ice cube. Most importantly has your tank fully cycled yet? If your water is good try crickets. Aro loves them. I normally fees my Aro with market prawns, super worm, froggies and cricket.

Will the arowana base color slowly disappear as the arowana get older ???

Thanks for the information. Icecube too :-)

Shouldn't fade..unless there is changes like background colour. . During growth from juvenile to adult, there will be changes

Guys, my fish eating problem still haven't solve. Now it like... sick ? Am not sure. But the fins getting darker.

Bro, I'll suggest you to lower down the water level first. Simply 5 times higher than the height of your aro's body length.

Before we go into details, would like to know the below:
1) What kind of media's are you using now?
2) How do you change water?
3) What are you using for the water changing?

if like that i scare the water from filter, output flow down and cause alot vibration to tank. And water not stable ?

What filter n pump are you using? OHF or Canister?

Canister, first 3layer put sponge then upper 2layer put carbon.
I change water using the rm5 handpump from fish shop. Then replace water directly from toilet with 10meter hose.
Put 1full spoon of salt. 1full cap of Anti Clorine, 2days ago put 4ml of blackwater, now almost clear already.

After 3days i changed. Just now:
30mins ago I changed water again. This time I dont use toilet water but I use Diamond water. The one i drink from the diamond water filter, ofcourse not boiled water.
Just now went Pets Wonderland and got a pH decrease liquid. Previously pH was 7.6+. Put 5ml into canister already. Just now that guy call me to take out coral stones in order not to let acid to produce. The temperature quite high, 31'c. So i threw few ice cubes in. LOL

Threw in 3pellets, 2worms daily. And 2 guppies and 1 ikan lambang inside.

Walao bro, dont play with blackwater n pH leh..No wonder your aro like this la...

1) If can, we dont use blackwater or pH down. Just use anti chlorine enough..As fluctuation in pH will kill your aro, unless you know what you are doing.
2) If your room temp is 31'C, just let it be. As its natural, my 6 feet tank average temp is around 30'C even at night and I dont use any heater unless my aro is sick.
3) Canister - U dont use any filter media like bio rings, coral chips? If you dont, I assume you dont know what is BB - Beneficiary Bacteria which is very very important to fight the bad bacteria and protect our aro.

i nvr play. i follow the instruction paper and pour. now pH is around 7.2

Oh ya. I threw away that 2years old bio rings just now. That guys say will produce acids ~
Maybe tmr ill get a new pack.

What i mean "play" is using booster or liquid adjuster which will change the pH in a very very short period of time. And this is quite high risk.

Ok, what you can do now, is
1) Stop using any blackwater or pH down liquid
2) Get some better quality bio rings from LFS and a bottle of bacteria booster (300ml to 500ml enough)
3) Put those bio rings in 2nd and 3rd layer from top. (Top 1st - wool/sponge, 2nd&3rd - bio rings, 4th - coral chips/lava rocks, 5th - carbon)
4) Then change water, put anti chlorine following the ratio
5) Add in Bacteria according to the instruction for new tank cycle

Note : Lower down the water level and sink your outlet into the water to reduce impact of water hitting the surface.

Then you sit back and observe the changes in your aro. No need bother the temp if the average room temp is around 30'C. Unless it's too cold like 25'C then you must monitor time to time esp Morning and Night then you need to use heater.

Bacteria that most of us are using . This is 2L one, u can buy a smaller one to try 1st.

Alright. Remember to buy those better quality but not those will drop off easily one. Else, your canister will be collecting dirt at the bottom or will pump into the tank.

Once again, remember to lower down the water level after you've change another round of water. Trust me, your aro will be more comfortable with that height.
