Clarity tower is a commercial foam fractionator. The link I supplied earlier is how you can DIY one for about $150-200. I need to build one soon for my own pond. Got most parts except the bio balls.

Bro, why go find old pic? Just take a pic of your current pond pic will do :)

Wow bro, show us when u are done with the DIY :D

Recently I discover my only ray having some weird behavior, swimming near the water surface at the back of the pond. Today saw her doing it again and decided to take video from my room... her behaviour worries me. why did she do that :( here is the video of her swimming near the water surface... sorry the video isnt very clear as I didnt open up my window as not to scare the fishes... any advise?

so far in my experience of keeping ray.. i only notice them do this for 2 reasons

1 ) other bottom dweller stress them so hard that they forced to stay above ground ( saw this from my female ray during mating time )


2) they like to play with the air bubbles..

in your case i think since no other ray in there and your female looks reasonably big i doubt other fishes are disturbing i think should be second reason - playing..

either ways as long the ray is eating & active. should be ok

Thks bro... is good to learn that she is just playing with the air bubbles :D

I will just keep her this way at the moment... only when the time is right, then I see if I can get her a 'partner' :D

Today is a sad day. My last tiger in the pond passed away unexpectedly... yesterday she was still eating very well and I never expect her to die this morning... Took her out and then I realised that she was already 15 inches big. Didn't really know that she had grown so big in the past years from a 6-7 inches tiger... in the pond, she looked small...
I think I will not have tigers anymore. From 7pieces to 0 is a bad experience for me... I hope no more casualties... RIP tiger...

sorry to hear that... condolences..

feel sad to see this happened, hope you can get over it soon..

Thanks bro... :)

Is really a sad day for me... my first AK red jumped out of the medication fgt after spending 2 nights in the fgt for treatment. I did put cover and heavy weight on it. However its powerful jumps somehow manage to toppled the weight and eventually broke itself "free"... and caused its death... my fault... my negligence...

RIP 小红... I will forever remember u...

If u would like to take a look at 小红, u can click the following to bring u to photobucket... sorry, I do not know of other way to load my pic yet...
