Went to independent fish shop today was having a look around, then I noticed some ember tetra and them looked at the price and you could have 5 for £8, was quite amazed. I have been holding out for some chilli rasbora due to there size but half tempted to get a group of 10 of these. I know they stay small and have looked into them before but Would these be ok for my tank considering it's only 60cm x 20cm x 20cm ?.
