my PH is around 6-7 (my ph test kits give different results) i have a 50 g tank. i want one that will most algae in general (i do know that whiptails eat some types of algae because as i said, i've kept them before) and will look pretty when grown up. i'm starting to change my views on the pleco because i heard they poop A LOT. i have 1 adult and 1 juvenile veil angel, 4 silvertips, 3 rummynose, 1 golden pencil, 8 kuhli loaches, and 2 yoyo loaches. please do not judge me for the fact that i have less than 10 of each of the schooling fish in my tank. they used to be 25+ silvertips and 40+ rummynose but then the rummynose, which was newly bought, turned out to be sick and killed majority of the fish i have. that's why i was asking for an algae eater because one of the disease's victims was my royal whiptail catfish. if you should say something, please do not worry because as soon as i go back to my LFS (in about 4 weeks), i'll add some more of them. thank you all for responding BTW!
