hi everyone! thought i'd check in with my recent updates. absolutely nothing has changed, lol. my levels have remained the same as always: three zebras for cycling ammonia 0.25 nitrites 0 nitrates 5-10. sigh. lol! it's been, what, about a month and a half now, i think. which isn't a very long time for cycling, but still. i'm really wondering why i haven't seen any changes yet. now...for another mystery...this is a good one..brace yourself...no making fun of me! i sat on the couch last night and admired my fish swimming all over the tank. all three danios were happily schooling along the waters, up and down, around the trees, in and out of the barnacle and castle, etc. no agitation, no signs of stress. i turned out the light canopy and went to work the night shift. i came home this morning at 8 am. went to admire the fish and get my equipment ready for my weekly water change. ...one of the danios is gone. and i'm talking GONE. he is seriously nowhere to be found. i dismantled the filter - not in there. i removed the barnacle, seashells and castle from the tank - gave them a good shake upside down, had a really good peek inside each one - not in there. not stuck to the light canopy. i gave the gravel a careful, gentle stirring throughout the tank and did not uncover him, supposing he got covered in gravel somehow...well, he's not there. the heater is just a simple submersible wand shaped device - nothing he could get stuck in. i searched the outside of the aquarium - the table it's sitting on, the surrounding floor area, under the table, etc. nowhere to be found. it is worth noting that i don't have much in the way of decorations in the tank, just smallish ones, so i didn't have much to search. so i proceeded with my weekly partial water change. about 25% or so using a 5 gallon bucket. as i vacuumed the gravel gently, i had another really good hard look around the bottom, beneath the gravel, in the corners of the tank, etc. i rustled up all of the gravel hoping to find him. nothing. he's the biggest danio, and he's very fast swimming, very powerful, seems to be the ring leader at times. so...it seems unlikely that the other two would randomly chase him down and eat him. my other two danios are just a small torpedo shape and there is nothing about their bodies to suggest they consumed a large quanity of food. their bodies are still slender, not distended at all. but even if they chased him down and killed him....where's the body? mind you, i really don't think they'd have been able to do that. he was considerably more robust. i left for work last night at 6 pm. returned this morning at 8 am. when i left, there was nothing to suggest that any fish was sick or sluggish. they seemed perfectly normal. is that a long enough period of time for the other danios to.....i don't know...hunt him down, kill him, break little pieces off to eat bite by bite...seems unlikely. they have the smallest little frigging mouths i've ever seen. if he died and wasn't eaten, how long would it take for him to decay? i'm assuming he wouldn't just totally disintegrate into nothing overnight. has anyone ever had a fish go missing? what were your theories? did you ever solve the puzzle? it's a sad day today - i really loved those fish - but on one hand i can't help but laugh a little...i mean...i lost a fish. he's long gone. i can't wrap my head around it! i asked my husband if maybe the fish died and he took him from the tank and won't tell me because he doesn't want to hurt me, lol, but he said no. i seriously have my doubts he'd do that, haha. i was just taking a shot in the dark. one theory i do have...and i mean, this is taking a real shot in the dark...is that perhaps my eyes were playing tricks on me last night and there were only two danios in the tank. perhaps i didn't notice for the last few days that a danio was missing. that seems unlikely because i lay back watching them quite a bit and i'm not an idiot, lol. but...perhaps. perhaps there were only two last night. perhaps the other one died the other day or something, and his body was at the top of the water, in the front of the tank, behind the lip of the canopy...know what i mean? a place where i wouldn't be able to see him unless i physically removed the entire canopy, which i haven't done lately until today. and then he decayed and disappeared, lol. i know that's a real long shot but i seriously have no idea what else to think!
