I bought the following about 2 years ago:
5 1/2 Gallon Kit - $50
Heater - $15
Thermometer - $3
Gravel - $10
Replacement Light Bulbs - $2
Dwarf Frogs, FanTail Goldfish, Sunburst Platies - $25
I bought two more aquariums this past month:
29 Gallon Tank & Wooden Stand Combo - $240
Included: 130
GPH filter, 100W heater, fluorescent hood
Gravel - $20
Decorations - $50
Platies - $5
The filter was inadequate and the heater couldn't keep the tank warm enough so I added the following:
AquaTech 330
GPH filter - $35
Another 100 W Heater - $20
10 Gallon Kit - $30
50W Heater - $15
Two Fluorescent Light Bulbs - $10
Used spare gravel from previous tanks
Decorations - $20
QT'd Platies - $10
Total Cost to Date: $560
Not bad considering it is over a two year period.
My 2 year old 5 1/2 tank was busted yesterday by the cats. They decided to run around and play by the tank.. which resulted in them slamming a solid wood door into the aquarium. Which shattered the front and made 3-4 gallons of water fly out.
Luckily I was able to save the four fish and put them in the 10 Gallon Tank for
QT.
Now I have the following spare items not in use because of the aquarium incident:
130
GPH HOB Whisper Filter
100
GPH HOB Whisper Filter
50W Hang on Back Heater <-- haven't tested it yet.. it might have died after the cats broke the tank and left it not submersed.
