I'm in the process of deciding which tank to buy but need a wee bit of advice if that's possible please. I'm thinking of going for a Juwel Trigon 190 but because of the shape I can't work out what the optimum number of fish (or more appropriately total fish length) would be.
Is there anyone out there with one of these tanks and can you help with the calculations for working out how many fish?
The usual formula for tropicals is 1" of fish per gallon of water. Is the tank 190ltrs.? If so 190/4.5(ltrs. per gal.)= 42.22, so a maximum of 42 fish. That's one inch fish, the bigger the fish the smaller the number. A lot depends on the size and type of filter you intend to use. In general, the bigger, the better.
HI masala, welcome You've already been given some sound advice, 1" per gallon for small-medium tropical fish is about right, but if you tell us what fish you plan on keeping we can advise you a bit better. Please consider doing a fish-free cycle, it is much kinder to the fish Anything else you need to know, please don't hesitate to ask.
Thanks for all of the prompt replies, it's appreciated!
We've now spent the evening rearranging our living room and have found space (if we need it) for a rectangular tank. Are there any advantages/disadvantages to having a rectangular tank versus a corner tank?
Also is there anything to beware of if we go for a second hand tank?
Can't say what fish we're thinking of getting yet - is it vitally important to decide if you're having say an Amazonian or Lake Malawi set up? Or can you do a general set up with fish you like??
I have 190 litre tank, we got it for my 6 year old son, he is autistic & absolutely loves fish!
Already in it we have 4 platys, 4 Dalmatian mollies & 6 dwarf rainbow fish. We are looking to add 4 dwarf gouramis & 2 small angels. Does anyone know if the tank is big enough to add the additional fish? For how big the tank is there doesn’t look like there is much in it just now.
