Hey guys/gals need some advice stocking my 23 gallon aquarium I'm thinking of getting 6-10 either neons,cardinals,serpaes or rummynose tetra , 4 zebra loach , 3-4 otocinclus and either a gbr pair , bolivian ram pair or apistogramma pair (I preffer gbr) only problem is I've never had any type of cichlid in my life I want to get german blues but hear their hard and I think it's £16 for two? and don't wanna waste money to see dead fish ... so I've been told to get Bolivians or a type of apistogramma So can I have some advice on that? And what schooling fish I should get out of what I chose or another schooling fish (i prefer tight schoolers) thanks :)
