Hello everyone, It's been a while since I last visited the forums. So I haven't been home since xmas, went abroad (studying in the UK) leaving my 2 tanks in the hands of my father. A 10 gallon with a HM betta and a planted 32g tank with 4 corys a GBR 10 harlequin rasboras and an angelfish. When I came back I wanted to cry! The betta died and the glass of 32g tank was FULL of algae and I couldn't really see anything inside! I cleaned the glass and I started counting fish. Only the cories died and 3 rasboras!!! I couldn't believe that the GBR survived and the cories died! Anyway I decided to get the 32g tank back in shape. I ordered some plants and completely rearranged the tank. The problem is now I don't have any cleaning crew in the tank! This is the first time i don't have cories but I am not buying more of them as they do die easily for some reason (maybe it's because the tank can reach 32C (~90F) ), I tried increasing the number of the harlequins. Bought 3 more and the angel ate them within 10 minutes! (only the new ones). I bought 3 nerite snails as a cleaning crew! Should I try adding any other fish or leave the tank as it is?
