Advice Needed

[samanthascott123]

Hi new to tropical fish keeping and was looking for some advice on adding new fish to the tank how many fish can be added at once when the tank has been set up for a few month. I seen a site selling starter packs of tropical fish containing roughly 18 fish would this not cause an ammonia spike? Thanks for any advice

Adding that amount of fish in one go would probably cause ammonia spikes yes, unless they were added at the end of a full fishless cycle, perhaps.

The usual guideline is to add no more than 50% of the tank's current stock in one go.

I've seen those 'tank filler' packs on a few sites, and they're always a very bad mix of unsuitable fish, IMO.

to the forum, btw

hard to tell if you had those fish for a month if so tell me but otherwise if it has been two weeks or more than i suppose you could add two or four fish...
btw,

oh okay now i see yah you could add fish
