question 1: what happen to it when water change? how you do it?
question 2: it look like you've set it indoor, closed from sunlight. Is it ok?

Cheers,

Hi gooner,chinaryukin

A typical siphon and 10m hose will be used to change the water. May left a bit old water and should not be any problem. Correct me if i were wrong.
There will be sunlight shining on the pond through the window from 8am to 12am. May give a try first. If the result is not good, may move the pond to outside. Hopes this answer your question.
Chinaryukin, your ranchus are very nice. Keep up the good job. I will collect mine this weekend. May need your care-taking help.
Thank you.

I think that is quite simple to take out the water.

Can suck out the majority of water with hose and the remaining and be taken out by sponge/cloth. Take a big bunch of old clothes and dump it in. It'll dry out the remaining water very quickly. even if some left behind, it should be ok. after use, rinse it with tap water. Maybe, can dry it by hanging on the fence behind the house. Sunlight and rain will kill whatever left behind and good for the next use. I've actually done that for my initial setup some time ago. Only few minutes extra of work. Easy jup!

Another tip, if you want to take out more water, tilt the tank a little by using some means of shim (thin wood, left over styrofoam, etc). You can leave the shim the permanently, no problem.

Sometimes we need to be flexible with the so called "rules of thumb".. for example.

- If water too hot, we can put shades or styrofoam or use fan.
- If rain kacau, put cover.
- If not enough sunlight, use metal halide.
- If water too cold, use heater.
- If temperature fluctation a lot, use styrofoam to stabilise the temperature
- If poor oxygen exchange, use fan

There'll be definately some hurdle with the setting up against our living place. But we can use something to overcome the constrain like the above mentioned examples.

Dear Sensei,
I having some problem lately.
I bought 20pcs babies ranchu from u and my friend took back 10pcs from me.
but since he took his ranchu back ,my babies seem to created this problem...they refused to eat and hide around air stone.

on the first day when they hv 20pcs,the eat like nobody busines and swimm happly in my 4feetX2feetX4inch high.
Now this 10 fish so scare and daily feed being reduced from 1 teaspoon until todated more than half teaspoon(i reduced half from my perivious feed since onli 10 fish).just got back and find some pellet still remain and when they see me all run like mad!!!.they onli eat 1 time a day in this few days....

what should i do.
here is my teori,
1)could be the number fish is small compare to the previuos fish..20 pcs?.
2)could the tank is too big for them?.

I hv double check,no white sopt and the water is o.k.how do make them back to the active mood?.

my solution:
1)can i reduced the water level in to 3 inch as now is 4 inch?.
2)can i divided in to half (2feetX2feet )using brick just to calm them?.

pls, advice me as I hv never xprience with this thing myself.thanks

Use 0.5% salinity water as pre-caution step (100% water change). Have you been feeding bloodworm? When was you last water change? Any predator around your place? During last water change, did you adjust temp before placing the fish in?

They group at airstone as you said; lying on floor of floating in middle?

4" water depth is ok.

during the time you split the fish. Did you chase the fish a lot with net/hand? It sound the fish is a little stressed up. Space is ok but you can reduce it by using a smaller tub (Quarantine use type) to prove your theory on space, it worth a try. When fish eating happily and sudden change like this means something is wrong along the way. Handling these fish need to be a little more gentle.

Stop feeding for a couple of days and observe any changes. Let me know the outcome please. Thanks

i didn't feed blood worm lately ,onli Masu and Ayu.My friend took on monday night ,oledi passed 4 days.the problem happen the 2nd days after they been reduced in number.I change water on sunday..shouldn't be problem i guess.

after observed quite some time ,i found out that they just look in the panic situation .just try my luck feed some food little far from them ,after 5 minutes didn't touch any food so i moved the air stone near the food ,onli some fish eat and all the pellet washes out from the air stone section.suck out all the remain food and took the air stone out of the water ,they run all over the tank in the panic form.onli when air stone put back in place,they slowly come near the air stone.

will add 0.5 % salinity and do some division on the tank .see how it goes.thanks.

Better use new water when you add any salt in. Make sure there's no temp shock during change over.

just change 100% water and add salinity as Vincent told me.do a check just now and some fish now slowly swim away from the air stone section ,rest still the same.hope for the best.no feed in the moment ,just observed and if tomorrow o.k ,will try on the feeding them.
