My Mom is giving me her 150 gal tank. I have a 70gal and a 50 gal already. The 50 gal has just plants in it i was trying to control the black hair algee i have had problems with it. The 70 gal has 2 gourami's; a plec ( actually 2 but one belongs in the other tank!) 2 rainbows a platy a sword tail and this fish i bought that said it was a cordydenra? but i dont think it is. Now the question is What would you do with a 150 gal? No salt water...never done that before .... plus the cost would kill me!
