my frogspawn seems to not be extending all the way. the calcium levels are 400 ppm, pH 8.3, nitrates, nitrites are 0 and ammonia is less than .25. they are usually 0 but there is a dead fish in the anenome's mouth at the moment. i have power compacts at the moment w/ 260 watts on a 55 gal. it usually extends all the way but the past couple of days it has not. looks like it shrank. for the people that have frogspawns, do you feed them? if you do, what? how often and so forth... do they need any other supplements?
