I have two rose bubble tips anemones. After I fed one, it lost the shape of bulb like tips. A few days later, its tentacle shape up to bulb like tips again. But the other anemone, I fed it the same thing as the other anemone, but it doesn't lose the shape of bulb like tips. It always has bulb like tips so far. Both of mine had low flow, or no flow at all lol. I moved my powerhead a few days ago, so now one of them has a little bit more flows.Maybe it just depends on the bubble tips anemones.
