first of all thanks for reading this. im new here as iv been on other forums but this one seems like the friendliest.
Iv kept goldfish all my life. recently my last one died so i now have a 50 litre tank with nothing in it (well i have a fluval pump i bought seperate, gravel and a sunken ship). i plan on buying a 100w tank heater by deltatherm, a new light and some plants. the fish i want to get include neon tetras, Pygmy gourami, small-medium sized catfish and a couple of shrimps. since this is the first time im going to get aquarium fish i need all the advice i can get before getting anything. is this combination ok? is there anything i must add? how often will i need to clean the tank (i used to take 25 - 50% water change every 2 weeks)? is there any special chems i need to add (i used to add chloride remover and water tonic to my tank)?
all feedback and comments is welcomed with open arms and i greatly appreciate you taking time out to read adn reply :)
