Forgot to introduce myself! People know me as Curly and I am Co admin for piranhaforum.co.uk and currently have a few tanks running with solo serra type piranha (1x Manueli, 1x Compressus, 1x Black Diamond Rhom), a community tank with Tiger barbs, Spanner barbs, Tinfoil barbs and some shrimp. Then I have another tank with 2x Orbignyi Rays, 2x Hydrolycus Tatuaia, 3x Silver Dollars and a Silver arowana.
All my tanks have two externals on as I am a big fan of over filtration but they still get weekly water changes.
My dream tank would be huge and house at least one Hydrolycus Armatus if I could get hold of one and a couple of rays. Plus another few tanks for my piranha's!
