The worst thing i had happen to me..
A long time ago my first 55 gal. started leaking. I got the tank from a friend who had it for who knows how long. After having it myself for about 3-4 years it started leaking all over the hardwood floor.
Of course this happend when i had been away for about week, so the only thing i could do at the time was have my dad take care of it, he was mad.
The only option was to put the fish in buckets with tank water, drain the rest of the tank, clean up the mess, then haul the fish off to the LFS who would take them for free of course. I lost some good fish on that one. Not to mention it buckled the floor.
A few years later after taking a break from fish keeping, being that i had filters, gravel decor, etc i decided to start up another 55 gal. tank which is the one i have now.
The whole tank splitting. cracking, leaking thing is a bummer. I want a bigger tank but i think anything over 100 gal. would have to be acrylic, which cost big $$. I dont want to wake up one day and find that much water on my floor from a glass tank leaking.
Most of us have been through it all, and the newbies are just starting the ride. I know i have been through alot over the years.
Tank leaking.
Leading to giving good fish away.
Didnt know about fishless cycling at first
Equpiment malfunctions.
Disease.
Power Failures.
Fish death. Etc. Etc.
Looking back though probably the most morally wrong tank i've ever had, back when i was a teenager and it was more than likely my first tank, back before i knew nothing and the LFS's would say "yeah that will work" just to get your bussiness.
The tank was a 20 gal. High with a Irridesent shark, Bala shark, Two kissing gourami's Two blue gourami's and a Channel catfish. I dont know how that tank and fish lasted as long as it (they) did, but i did. Even with no water changes except every six months.
Now that i think about it, it may have been a 29 gal. but that still does not make it right.
Live and Learn. Thats the moral of the story.
