HELP!!! my friend who is 14, like me, has a 12 gallon biocube. he had it up and running with a 3" rainbow shark, a bristlenose pleco and a bunch of guppies, (he had more fish but they died off over time). I was giving my friend information about fish because i am addicted to fish keeping, i did and still am doing a bunch of research, i have 2 tanks set up, a 125 with arowana, eartheaters, uaru, and some plecos, and a 20 gallon discus tank. so anyway, my friend told me yesterday that he was doing a 50-75% waterchange at least every three weeks!!! he also told me he washed out ALL of the filter media including the BACTERIA!!! i told him he should be doing maybe a 25% water change every week or so, and not to rise out the bacteria. he said ok. so today he called and told me that he cleaned out his tank yesterday and supposenly put decholinated water back into the tank and two hours later all of his fish were dead. even the pleco.
he then told me that today he went to a fish store and bought new fish. i dont even know if he changed the water again before he bought new fish. and guess what fish he bought, three fish i dont know what kind, but then two bgk.... all this week ive been telling him that he can only get fish that are small (because i dont want him to get fish that get huge only to have them die) so i told him just a little while ago that the bgk get about 1 1/2 to 2 feet and he said "Ya i know" all happyish... that just made me mad... but i said o well.
so i told my mom, she seemed upset because she hates to see/hear anything die and she doesnt want animals to die. then my mom told me that my friend's (same friend above^) mom called my mom a long time ago and said that i knew too much and that i was telling my friend what to do.... (when i heard this i was mad as heck all i was trying to do was to inform my friend what he can and cannot get because of size, hardiness, etc.) and then my friends mom said that i just need to let other people learn things on their own...... and i was like ***k that i dont want any fish to die because of my careless friend. god i wish my friend wasnt so spoiled.
what should i do, i dont want this to ruin my friendship with this friend, but i dont want any fish to die!
