Hi guy, Im hector , Im new here, i just want to say all the information that people have provided on this site are great. I have never kept frsh water rays before but this forum has got me hooked. I have a few questions on filtration, I plan on buying a 125 gallon tank and I plan to house 3 retics, 1 male 2 females , and 4 polytherus senegals and maybe 2 sevrums. I know it's small but if the rays get to big ill get another tank. I was planning on getting wet dry but is it necessary or can i go with 2 canisters. I plan on doing 50% water change every week, with the large water change are the canisters fine or should i go with the wet dry. I am new to sting rays but I have kept marine fish, africans and large south american cichlids. I just want to know if the wet dry is overkill. thanks .
sorry i cant pm you yet . site wont let me .
