Filters for larvaes, yay or nay??

[RyooLovesNewties]

So yesterday i just bought 3 Tylototryton larvaes and plan to add a filter.I put the filter in before the newts, i used an internal waterfall filter. so when i put one larva in it just kind of got sucked (fortunately there is no injury) into the filter, for now im not using any filters. so should i just use the filter or pass the filter OR change it to any filter that is more suitable??? and also if i still want to use the waterfall, is there any idea to block it so they cant get sucked?

I did a little searching for threads thats talking about this and i just can decide what is better, so im posting this for assurance!!
