Hi Pegasus,
I have an AR126 and all the angels are quite small about 3-4 cm nose to tail i have just bought two more so in my tank i have as follows
1 koi angel
1 black angel
1 platinum angel
1 Silver Angel
1 gold angel
3 black phantom tetras
5 neons
1 pleco
1 bristlenose
2 clown loaches
i have talked to a few people and they say i am not overstocking and i wil have to give back the engels when they are bigger, though i should have my AR 620T by then
