well ive been planning a plywood build for a while now, i have been sourcing some parts and prices but im moving house soon so cant really start it yet, trust me it will happen though... it is clean and all the parameters are good at the moment. im running an fx5 and a big powerhead, i also do a big waterchange weekly. ive had most of them for a while and have always planned on reducing the stock down to my favourites as i go, which i have been doing, im getting better slowely at not buying a fish everytime i go to a store lol. im not a every fish i buy for life person and my good lfs give me good credit on any un wanted fish. i know dovii are documented as getting huge in the wild but very few captive dovii get much larger than a big oscar, what do oscars top out at 15, 18 inch! takes a long time to grow so i figure i have plenty of time, i like a busy tank and if either the dovii, rd, or butti start getting mean i have spare cash for a temperary tank and a big solid stone 3 inch thick slated divider which i made, if something more immediate is needed... i have kept fish for 15 years, the conditions are good and the all get on with each other at the moment so im happy with that, i would never keep them all in there when they were fully grown, and its far from overcrowded atm in my opinion. please i dont want get into a debate as to whether i know what im doing or am a good or bad fish keeper.
