Bulb anemone and bubble tip anemone are usually used interchangably and it is very confusing. The site lists both and bulb "Gyrostoma Quadricolor" and bubble tip "Entacmaea quadricolor". Neither are natural hosts for perculas. Natural host anemone for percs are either very difficult to keep, prohibitively expensive or grow very large. If this will be your first anemone a bta would be a good choice. There is that chance that your fish won't host in it but there is a chance it will. If it does host may take some time, could take days, weeks, months, a year, maybe never. I have a juvinelle perc that hosts a bta, it took a few weeks.
