There all at 5'' inches right now. If I starved them out for two day's and try a little pellet's at that time because I have to feed the fire mouth do you think that would hurt? And maybe if it doesn't work just give them some Blood Worm like one or two cubes for five P's and then another two day's starve em out and try again, and if it doesn't work then try again in another month and half? They same way I tried this time again at that time in a month and a half? Let me know.
