I am in the process of re-setting up my Betta's aquarium. I have a White Halfmoon Plakat Betta that I ordered/received from Thailand (might as well go to the source! - besides I used to live in Bangkok and just looking at 'Mai Khao ' [White Silk - his name] reminds me of my time there). Made some mistakes the first go around which got my baby a little sick, but he is isolated now and is recovering.
3 gallon, 7.5" diameter x 30" high cylinder vase (I don't have room/space for anything larger)
Lee's Round Undergravel Bowl Filter (2 gallon)
Penn-Plax Smallworld Filter (SWF-1)
I have lengthened the uptube on the undergravel filter so that the air bubbles (powering the filter) are closer to the top so as to not create too much current in the entire tank. Of course the tubes available were too big in diameter but I was able to make them stay in place (both at the base and at the top where the carbon cartridge attaches) but cutting small pieces of activated carbon 'sponge' and wrapping the 'male' parts prior to inserting them into the longer uptube.
I am looking at getting the Hydro 7.5 Watt Slim Heater for Bettas & Bowls
(designed for 2-5 gallon) to raise the temp a bit.
Also am in the process of finding a small piece of Malaysian driftwood that I can attach some Java Fern to (made the mistake already of buying 'Lucky Bamboo' from PetSmart [never buying local/big box store again] but it just rotted - learned my lesson).
I am wondering if I could/should add some bio rings underneath the undergravel filter to aid the bio filter (as the Smallworld replacement filtration units' are disposable and each time I replace them, all the good stuff goes out with the old unit. Feedback?
Also, what kind of gravel should I use? Currently I am using some beach glass (not sure how wise that is but I like the look and my Betta seems to be okay with it and enjoys it). They are large, smooth pieces that do not effect his fins.
Finally - Mai Khao is very picky when it comes to his food. Since he is white (not albino) I have found it very difficult to find food that isn't 'color enhancing' - and irregardless he just won't eat it. All he will eat is frozen glassworms (mosquito larve) but not sure he is getting enough protein (though that I know is their primary diet in the wild).
Any input/comments are appreciated. Thanks.
