  • We are currently upgrading MFK. thanks! -neo
we gota place like that down the road from us. their expertise certainly arnt in the fish keeping dept! il tell u the fish that are in the 'pond' and u guess why they have this dept.
2 pacus
1 plec
2 rtcs
1 oscar
take a wild guess lol they also have some terrapins...samwe reason i guess and a 125g of piranhas lol....its embarassing!
 
No offence to anyone from the UK Chloe but I've been to a good number of "aquariums" and zoos there last year and can honestly say that your country needs some serious lessons in taking good care of their animals... The london Zoos giraffe enclosure is a PERFECT Example... giraffe tanks 2 steps to the right and it's a fence...2 steps to the left...Fence...2 forward or 2 back and guess what ... building and a fence LOL they need space to run... and then to have 3 of them stuffed in that space is horrible.

There is a "aquarium" in Brighton (Across from the Brighton pier)...Sorry but to have the Wels in that small of a tank is just an insult.

All aquariums have issues to deal with but this was just a very costly mistake (costly in lives and money) and I'm sure that they will take the proper precautions to ensure that this type of thing doesn't happen again (Although I thought that all public aqauriums would have their water parameters being constantly checked via automated systems... personally I would rather spend some cash on a Dissolved Oxygen Meter with a alarm than risk losing 40+ rays
 
While I don't know the story behind this, I believe that they should have put another pump in there or enough smaller pumps, if they didn't have the big ones on hand, to supplement that broken pump.
 
Being in Calgary we watched that story carefully. CBC has blown that out of proportion, the zoo has never hid anything bout this. Unfortunately there never was a definitive answer about what happened. I always wondered if hundreds of dirty people every day touching the rays had anything to do with it. I'm happy that are going to have rays again, but I sure hope they learned their lesson.
 
I think any public display worth it's weight should have backup systems for ALL of their systems, Water change systems, oxygenation systems, filtration systems, power systems ect...hell alot of us with decent size aquariums have back ups for our "what ifs" that happen

guess you guys missed the part where they said one of the pumps went down.... god forbid a person makes mistakes... i pass no judgement on them for it... some people need to pull there head out of there and move on get over it or go cry a river somewhere... they could of just kept it to themselves but the stepped up and admitted it.... bet none of you have ever made a mistake in your lives...

Chalk it up to shibby happens. I just hope something was learned...... Like perhaps overkill is good. If there was twice as much aeration as there should be then half of it could fail and they would still be fine.

Perfect example why it makes me nervous only running one pump on my pond.......
 
OK OK the Zoo did hire some one to design and build the ray encloser. Some one who had experience with building ray enclosers??? I for one agree with the zoo comming forward with the results and taking the flak. The calgary zoo is quite impressive and has some of the finest and beautiful enclosers i've ever seen. I'll post some pictures when i go in the spring i'll post some pictures.

Yup.. people with several thousand dollar setups have backup parts on hand, a zoo with a several hundred thousand dollar setup should, too. It's simple common sense.

And then when prices to get in triple (or more), zoos/aquarium close because nobody comes.


Most have a lot of off exhibit holdings. All of them have back up and contingency plans. However, just like home tanks, you can't cover 100% of everything that MIGHT happen. And with the scale of these big displays, it's not like dropping in an airstone and adding a hang on the back filter will work. When a major system goes down, it's months worth of work and hundreds of man hours to recover. Just adding a new filter can take a month or more.
