Hello i am getting my new tank soon it will be 55 gal i am so excited my tank now is a 20 gal - i have a few q's though - i currently have a few platies, a pleco, angel fish (which is getting huge) , some ottos and some albino cories as well as 3 different gouramies - i know currently i'm slighly overstocked - so i will be moving them into the 55 i want to get some silver dollars , pictus cats and clown loaches - i want to move into a more semi aggresive tank - i know my gouramies will be ok but will the sivlers beat up on my platies or will they be ok? also will pictus cats hurt my cories or will they be ok - i have 3 cories thinking of getting more , but i want two pictus cats - i want this 55 to be a pleasant tank with a slightly semi aggresive touch as i will be moving away from keeping platies etc - however i dont want to hurt the ones i have currently - thank for your help also pls give me some other suggestions if you have some!!! i'm also thinking of maybe gertting some schooling tetras!!! i obviously wont have all of these in there att he same time im jsut thinking out my options !!!
