Frequently asked questions
Most classic community tetras — ember, emperor, glowlight types, Colombian — sit between £2 and £5 per fish, so a proper school of ten is £20-£50. Wild-caught and collector species cost more. Prices below are live: what's listed is what's in stock today.
Ember, emperor and Colombian tetras are the forgiving picks — small, hardy and unfussed by typical UK water. Neons and cardinals are just as keepable but want a mature, fully cycled tank first, so make them the second addition, never the fish that opens a new setup.
Ten or more of the same species is the honest minimum — six is survivable but you'll see nervous, washed-out fish. In a big school tetras swim in open water, colour up fully and show the coordinated shoaling behaviour you bought them for. Budget schools, not pairs.
Side by side, absolutely — embers over the plants, emperors mid-water, pencilfish at the surface makes a beautiful layered tank. But each species only schools with its own kind, so buy 8-10 of each rather than three of many. Mixed singles never form a shoal.
Less forgiving than neons. Cardinals want warm (23-27°C), soft, acidic water and a mature tank, and wild-caught imports need careful acclimatisation. Captive-bred cardinals — which is what we stock when available — are noticeably tougher. Treat them as a fish for the settled tank, not the new one.
