Hey i have had a Juwel Rekord 96 for just under 5 years now. The tank started out as a livebearer tank full of guppies etc but for the last year or so it has contained cardinal tetras, black nean tetras, 2 clown plecs and 2 german blue rams which i was told when i bought them about 9 months ago that they where 2 females. I am thinking that they are actually more likely 2 males as they were v.young when i first got them and now both have a near solid black mark on the sides and spikey dorsal fins. They seem to have half the tank each rarely venturing into the other half. I have persuaded my parents after months to let me upgrade however the catch is that i have to get rid of the 96. They specified a tank around a meter long but they have not set a limit on height nor depth. The current tank has the internal filter removed and has a Tetratec EX700 currently as its soul filtration. Ideally in the new tank i would like a pair of angel fish. All the current fish would be going into the new one as well as a few others to go along side them. What tank do you guys think would be good? i can afford up to around the Juwel Rio 240 range. Any ideas? also what would the stocking density of the rio 240 be?
