No its not a Bio one, the undergravels just came with the tank.....
Came home today and i have lost every single fish in one day over ten fish...
Just bought a new tank so here we go start again.....got me fish poh anyway.
so sad....
I have spokento a local fish shop to obtain some mature media and i have been advised to just put fish doo doo in as i have an underwater gravel filter.....for free...
Hope this works.
Hi people
Just joined a minute ago and so glad this forum exists.
I have a small 30 litre tank and its been set up around 9 weeks....at first i was losing a lot of fish but i took this as just because the tank was new. My Neon tetras were dying, rummy noses a catfish and something else i cant...
